![]() What is happening is that WB Mechanical is not 'aware' of what a Commands Object is doing with respect to the FEM. I think that this kind of default setting might be quite dangerous in some scenarios. What I'm doing wrong, should the beam be remeshed in some way to add the additional cell points ?Īnother interesting thing is that why beam188 and beam189 elements doesn't take in account flexure-related shear stresses in addition to shear stresses caused by torsion by default -> KEYOPT,N,4,2 ? By default beam elements calculates only shear stresses caused by torsion ->KEYOPT,N,4,0. I think that this command object adds the cross-sectional cells, but when post-processing for example the von Mises stress results, they are nonsense. I have added APDL commands object under static structural to increase cross-section's cell count from 4(2X2) to 36(6X6) and also taking account warping and shear stresses from transverse shearing with following content: ![]() For example when using rectangular cross-section for beam element the default cell count along width and height is 2 -> "SECDATA,50,100,2,2". ![]() I know that it is possible to add more cells to beam element's (for example BEAM188 or BEAM189) cross-section with SECDATA command, but after using SECDATA the results of the calculation is nonsence. ![]()
