How to deal with it

Circuit.pas

7006

'tear_circuit','metis cannot start.',             'the metis program is not supported in fpc; tfilesearchreplace is unavailable.'

The user is trying to tear apart the circuit model either for creating sub-circuits or for using A-Diakoptics. This process required the Metis application within the OpenDSS Directory but is not there. Check if the file is in there and try again.

Circuit.pas

7007

'tear_circuit','the graph file is incorrect.',                   'metis cannot process the graph file because is incorrect' +                   '(the number of edges is incorrect).'

When tearing the circuit model using the incidence matrix produced by OpenDSS there was an issue. Metis returned an error message indicating that the graph is incorrect. Look for isolated areas and try again.

Circuit.pas

424

'tdsscircuit.addbus', 'busname for object "' + activecktelement.name + '" is null.',                  'error in definition of object.'

When declaring an element, it is important to provide an accurate description of the connection to the bus. This message signals that the bus definition is incorrect, either because it has special characters in the name such as dots (.) or spaces ( ) additional to the standard declaration. Review this features and try again.

CktElement.pas

751

'something is wrong.  got to base cktelement getcurrents for object:'+crlf+dssclassname+'.'+name,               'n/a',               'should not be able to get here. probable programming error.'

There was a problem calculating the active element’s currents, this can be triggered due to an issue in the last solution. There was no solution, or the voltage vector is equal to 0 at the connection points of the element. Check if the last solution converged and try again.

CktElement.pas

752

'something is wrong.  got to base cktelement getinjcurrents for object:'+crlf+dssclassname+'.'+name, '****',               'should not be able to get here. probable programming error.'

There was a problem retrieving the active element’s injection currents, this can be triggered due to an issue in the last solution. There was no solution, or the voltage vector is equal to 0 at the connection points of the element. Check if the last solution converged and try again. If the problem is not solved, there must be an internal issue that needs to be reviewed.

CktElement.pas

753

('improper call to injcurrents for element: ' + name + '.'), '****',        'called cktelement class base function instead of actual.'

The element declaration is not adequate or the procedure for retrieving the active element’s injection currents vector is not correct. This is an internal error and likely to be produced due to an error in the declaration/implementation of a new functionality.

DSSClass.pas

780

'reached base class of tdssclass for device "'+objname+'"',                   'n/a',                   'should be overridden.'

The element declared does not overrides the procedures/functions that should be part of the unit’s base. This error is triggered when creating new objects within OpenDSS and is telling the developer that the unit is incomplete, suggesting that one or several inherited procedures/functions need to be override.

DSSGlobals.pas

906

'makenewcircuit',                      'cannot create new circuit.',                      'max. circuits exceeded.'+crlf+                      '(max no. of circuits='+inttostr(maxcircuits)+')'

When cloning an existing circuit or compiling a new one in a different actor there is a limit in the number of threads (Actors) that can be created. In OpenDSS the limit is the number of threads available per processor, this to guarantee dedicated resources when doing things like Real-time. However, if users feel confident, they can remove this constraint from the code to generate their own versions. This is not critical, but a reminder of this constraint added.

('getcurrents for element: ' + name + '.'), e.message,        'inadequate storage allotted for circuit element.'

When declaring a new VSConverter, the number of phases is not declared correctly, producing an error in the vector-like properties memory allocation. Getting here is very unlikely, review the values provided and if does not work, reach out to the developer. 

VSource.pas

325

'tvsourceobj.calcyprim', 'matrix inversion error for vsource "' + name + '"',                   'invalid impedance specified. replaced with small resistance.'

When calculating the Y primitive of an element it turned out to be not invertible. The issue can be the result of a bad selection of impedance values or a typo when entering them. Review the values entered and try again.

When declaring a new VSource, the number of phases is not declared correctly, producing an error in the vector-like properties memory allocation. Getting here is very unlikely, review the values provided and if does not work, reach out to the developer. 

WindGen.pas

568

'windgen object: "' + name + '" in getinjcurrents function.',                    e.message,                   'current buffer not big enough.'

When declaring a new WindGen, the number of phases is not declared correctly, producing an error in the vector-like properties memory allocation. Getting here is very unlikely, review the values provided and if does not work, reach out to the developer. 

AutoTrans.pas

117

'tautotransobj.calcyprim', 'matrix inversion error for autotrans "' + name + '"',                    'invalid impedance specified. replaced with tiny conductance to ground.'

When calculating the Y primitive of an element it turned out to be not invertible. The issue can be the result of a bad selection of impedance values or a typo when entering them. Review the values entered and try again.

fuse.pas

404

'fuse: "' + name + '"',                                 'terminal no. "' +'" does not exist.',                                 're-specify terminal no.'

The user is declaring a fuse, but the observed element’s terminal assigned for metering does not exist. Check if there is a typo in the terminal number entered for the observed element provided and make sure the element was declared before the fuse declaration.

fuse.pas

405

'fuse: "' + self.name + '"', 'cktelement element "'+ elementname + '" not found.',                            ' element must be defined previously.'

The user is declaring a new fuse, but the controlled element assigned for control purposes does not exist in the active circuit. Check if there is a typo in the element’s name provided and make sure the element was declared before the fuse declaration. 

Line.pas

183

'tlineobj.calcyprim', 'matrix inversion error for line "' + name + '"',                         'invalid impedance specified. replaced with tiny conductance.'

When calculating the Y primitive of an element it turned out to be not invertible. The issue can be the result of a bad selection of impedance values or a typo when entering them. Review the values entered and try again.

PDElement.pas

660

('trying to get currents for element: ' + name + '.'), e.message,        'has the circuit been solved?'

There was a problem calculating the active element’s currents, this can be triggered due to an issue in the last solution. There was no solution, or the voltage vector is equal to 0 at the connection points of the element. Check if the last solution converged and try again.
