I am doing linear static structural optimization (topology optimization) of a plastic injection mold. I have the temperature of surfaces of my geometry. I used them as thermal load. Can I combine structural optimization with thermal analysis? Does Optistruct combine the displacement due to pressure applied to the model with thermal expansion?
1:
I created a load collector with card image of load to combine my pressure load and thermal load is that correct? I also have gravity. I entered 3 for the LOAD_Num_set. because I wanted to combine pressure, gravity and thermal load. Is that right?
For the loadsteps: type of analysis is linear static. I have checked SPC and selected constraint. I checked Load and I selected the load that I created which is combination of gravity pressure and temperature. Do I need to check TEMP and select my thermal load?
2:
My second approach is this
I created a load collector with card image of load to combine my pressure and gravity. I entered 2 for the LOAD_Num_set. and I combined gravity and pressure.
For the loadsteps: type of analysis is linear static. I have checked SPC and selected constraint. I checked Load and I selected the load that I created which is combination of gravity and pressure. I checked TEMP and I selected thermal load.
I was wondering which one is right, 1 or 2?
I got this message when I run the model
