Hi all, I have been working on a model lately and it can best be described simply as a 2-D flat plate. I've been running some fairly simple tests just to see how the solver deals with loads applied to a system and how changes in these loads affect the end (optimized) result. One test I've wanted to try yet haven't figured out yet is the linear distributed load across the top plate. Thus far I have only used constant distributed loads (Ex: 50 N force across all of the top edge nodes). When searching through these forums and online, I've heard of two ways of going about this. The first is using the "equation" tab inside the force panel. My model is set up in the (x-direction and y-direction) so I'm not entirely sure how the load should be applied as an equation. I've tried a few equations of my own (x, x^2, and 2*x) but haven't had any luck. The second method (which I heard by word of mouth) was to use Excel in a way that accounts for every node one would apply a load to along with the corresponding value of the force at that node. I know much less about the specific process for this one so if anyone has any direction here, that would be fantastic. All and any advice is welcomed and thank you in advance. Please let me know if you need more details about the model if it would better explain the current situation! Dylan Stelzer [:^D]
Hello, I currently have finished a model that contains structural and thermal loading. I used OS to conduct an optimization run and came out with a density model at the end. I created a new page in HyperMesh, went to the OSSmooth model, and performed the procedure to run the post-processing tool (FEA Reanalysis, put in the .fem file, put in the .sh file, set the threshold to 0.5, etc. etc.). After doing all of this and running OSSmooth, I end up with the final iteration model that I saw in HyperView, with almost the exact same BC's, materials, and loadsteps...the problem then seems to be that there are a few things that didn't transfer over. There is an error in the conduction interface card (3rd column of CHBDYE) and none of the heat SPC's or heat loads (flux) transferred over to the model but all of the force SPC's and force loads did. Why did the all of the force transfer correctly but none of the thermal? I'm investigating the problem currently but if anyone has any insight or help for this same type of problem, anything is appreciated. Thanks! Dylan Stelzer
