I am working on solid mechanics, frequency domain model. In finite study of a model, I checked all the material property, boundary conditions and meshing, everything is perfect but again I am getting "Undefined value found". Undefiend value found in equation of residual vector. After checking step by step, It is found that by removing PML, computation run and solution is obtained but when I apply PML eventhough other BCs are disabaled, mentioned error is appearing. So inshort this error is due to PML so far I observed. If anyone can help me in this regard how I can solve this problem ? As from COMSOL forums I understand, PML should work perfectly for frequency domain analysis.
Thanks in advance. Please check the attach file for detail of error.
