In a non linear plane stress analysis (sol 106, sol 601 or multiphysics), I want deflection only due to structural load. Thermal deflections and thermal stress should be neglected. How can I do this in NX 10?
Note: Material properties are temperature dependant and at different time steps temperature is different.
Solved! Go to Solution.
I switched off thermal strain by 'Non-linear control parameters>edit>THRMST=NO' and I am getting results which is equal to actual result multiplied by E-3.
If I solve for single time step by keeping initial temperature and load temperature same (to avoid thermal strain without switching off thermal strain calculation) I am getting correct results.
Why this happens?
Any time results are off by exactly 1E3, a units issue would be the prime suspect. make sure forces are entered in mN or N as expected. Make sure displacements are being read as m or mm as appropriate.
