Hi all,

i have a basic but most important question. i have created a plate of rectangular section. i have restrain one face & apply some force on the other side.

Now when i take the full model and analysis the part it gives some result. but when i take symmetry condition, it will give some deviation.

so finally my question is during taking the symmetry it deviates from it results. so is it safe to take the symmetry for analysis?

Did you check if your mesh size is same for the full model and the half model?

Also you may need to check if your symmetry (half-cutting) plane is not cutting across any elements in your original full model mesh, but rather it should cut at the nodes between each adjacent elements, so that you have equal mesh profiles in both half models.

From my experience, the change in mesh size has some impact on the results - and it could be that you are facing the same issue
