I have been asked to run a linear static study on solidworks on a joystick assembly as my colleague was strugling using Comsol.
I have ran my studies succesfully and as part of a sanity check my colleague has run a very simplified model with only two mating compoents included in the study, I have carried out the same study using the same setup.
Both my result and my colleague using comsol have identical results using linear elements. However he has run another study on Comsol with quadratic elements which show higher stresses and displacements.
However, my colleague has run a seperate study with the same BC's but with a quadratic elements in regards to the mesh setup.
Am I right in saying that this is just the number of jacobian points in the mesh element plot?
I am ran the same study with 4, 16 and 29 points and all results are identical? (Solver time is the same also.)
Any feedback woudl be greatly appriciated.
