Topology optimization with a nonlinear contact and temperature load
Dear Ladies and Gentleman.
I want to make a topology optimization of the following slider:
At E,G,D and F there is a guiding wich is made of plastics. The outerside of the guiding is fixed and there is a frictionless contact to the slider. On B there is a trapezoidal pressure load. On the C there is a cylider, so the displacement in x-direction is 0.
There is a thermal load on the body which you can see in following picture:
When I want to make a topology optimization of the slider I get following message:
" *** ERROR ***
Nonlinear contact in combination with thermal load is not supported."
The problem is that I need this nonlinear contact behaviour so that the slider can take off from the guidance.
Has anyone an idea how I can modell the thermal load or the nonlinear contact to get an acceptable result?
Looking forward for you answers.
