Hello,
I am doing a „3 point bending“ experiment, where I measure various deflections for a range of applied forces from 1-18N. For example: at 9N the deflection is 2.4 mm
I also simulated the experiment in ANSYS and COMSOL.
The first simulation I made in ANSYS 14.0 workbench and achieved good simulation results (for example at 9N the deflection was 2.49mm - close to experimental results)
Now I implemented the model in COMSOL, but the beam deflection only is 0.76mm at 9N. The material characteristics are the same as in the ANSYS simulation. I would like to use COMSOL for further simulations because it will be coupled with electrical measurements and other multiphysics and it seems that COMSOL is doing a good job with that.
Why is the COMSOL simulation result so different from the ANSYS simulation/real experiment?
Best regards
