    Lattice structure

    Dear @Ivan Thank you for your help. I have tried to change the force to linear static and the design is feasible but I cannot see the lattice part in HyperMesh. could you please take a look at my file. HM37_optimized.fem

    Lattice structure

    Eventhogh I had changed the constraints above 200 again I have the following errors. First: ANALYSIS COMPLETED. OPTIMIZATION HAS CONVERGED. INFEASIBLE DESIGN (AT LEAST ONE CONSTRAINT VIOLATED). Then: ANALYSIS COMPLETED. *** INTERNAL PROGRAMMING ERROR *** in file "dsetio-inc.h", at location # 132.

    Dear @Ivan I also use the 2017.2 student version. Thank you for your help, I completely understand what are the problems.

    Lattice structure

    Dear @Ivan I tried the solution you suggested. But There is another error. would you please take look at my file? 45x45x100 bulk.hm

    Lattice structure

    Dear @Ivan Thank you for the information. My model is supposed to simulate a compression test with enforced displacement. According to the file, you uploaded it is not possible to put constraint limit with this type of displacement. So, what do you suggest as a possible solution wrt this fact that I need to do this simulation with displacement percentage?

    Lattice structure

    Hello again, I just tried to do a lattice optimization for a bulk model under compression but I encountered the message below. I have also attached my file could you please help me to understand what is the problem. Thank you. 45x45x100 bulk.hm

    Dear @Rahul R This is the fem file without lattice. ctrlarm.fem

    Lattice structure

    Hi, I just tried to use optisruct to do the lattice structure optimization. The lattice fem file was created but I am not able to see the lattice parts in the model. Could you please take a look at my file to see if I did it correctly or not and what is the problem. I used the lattice option in topology panel(I have attached the photo of it). ctrlarm_lattice.fem

    Model files

    Hi, I need the model file for the tutorial OS-3300: Using the Lattice Optimization Process in OptiStruct. Thank you,

    Metal foam density

    @Pranav Hari Hi, I have the model of Al7075 foam I just need to measure the fraction of void and material, defining a density for the entire volume (it will be obviously lower than the bulk material one, due to the presence of voids). You can find the file in the attachment. Simulazione_mesoscala_Voronoi (1).hm

    Metal foam density

    Hi, Is it possible to calculate voids density in Al foam using hyper works. Actually I have the model but. I do not know how to calculate viod/material fraction.

    Compression Test

    Thank you @Ivan. I really appreciate your help. I understand what I have done wrong.

    Compression Test

    Hello, I am new to hyperworks and I have an issue that I couldn't solve it for a week. I had tried to do a compression test simulation on AL6061 but Even though I defined MATS1, NLPARM, And SPCD the result is zero. I modeled another file and it is full of errors that I couldn't find the source of them. Could you please just take a look to my models. Thank you, FarzadCompression.hmCompression.hm compression test.hm

    I need to run solver manager

    The simple way to show my problem is the tutorial : OS-3300: Using the Lattice Optimization Process in OptiStruct
