About Coordinate Scaling in Elmer Plugin in Salome
Posted: 17 Sep 2021, 05:33
Hello,
I built geometries in Salome and tried to use coordinate scaling factor for FEM analysis in Elmer. I got effective resistance for a box. But I do not know how shall I calculate the resistivity. I know the surface area of the cross section in Salome. Should I multiply the surface area by the coordinate scaling factor once or twice? Please check the following equation. Thank you.
1) Resistivity=[Resistance*S(Electrode cross-section Surface area)*coordinate scaling factor ]/(Length*coordinate scaling factor)=Resistance*S/L
2) Resistivity=[Resistance*S(Electrode cross-section Surface area)*coordinate scaling factor* coordinate scaling factor]/(Length*coordinate scaling factor)=Resistance*S*coordinate scaling factor/L
