OS-HM-T: 3000 Rubber Ring Crush and Slide using Self-Contact
Hallo, I am unable to get the simulation to converge after the rubber hits itself in this torturial. No matter if i increase the convergence limit, the minimum timestep and the amount of iterations it can do… and I feel i have adjusted everything else twice also. If anyone wants to help, it would be greatly appreciated.…

HyperStudy Tips and Tricks: #33 - HyperView Model Connection in HyperStudy
Hello HyperStudy users, HyperStudy reads results of a complete CAE model & defining output responses on specific components & sets (nodes/elements) is not available by default. Also, HyperStudy cannot add output responses for specific HyperView post-processing settings such as Corner Data, Averaging etc. by default. Hence,…

Inquiry About Sequential Evaluation and Stopping Criteria in HyperStudy
I am using HyperStudy for a multi-objective optimization project where each objective is calculated independently. Currently, my process is as follows: I have set up three objectives (Objective 1, Objective 2, and Objective 3). Each objective is evaluated through separate solver calls. HyperStudy first runs the solver for…

Optistruct ERROR:Not enough memory
Hello, I'm running a NVH model using infinite element and MFOUR method, there is an error: Not enough memory. The Estimated Memory (RAM) for In-Core Solution is only 21583 MB, but the MAXIMUM MEMORY USED is 266791 MB, is this normal? Is there any other way to reduce memory usage besides reducing the number of elements？ The…

Modelling a nodal spring in Altair hyper works (Optistruct)
Hello, I am attempting to model a concrete slab that rests on soil, and I wish to represent the soil using spring elements. I would like to know which spring element type I should use to define the stiffness in the x, y, and z directions (Kx, Ky, and Kz). I have tried using CBUSH and CBUSH1D elements, but I have found that…

Can someone guide me on how to obtain strain results in my analysis?"
I am currently using a software tool (e.g., HyperWorks or OptiStruct) to perform finite element analysis. In class, the professor required us to calculate element stresses, strain, and displacement. however, I was able to view stress and displacement results, but I don't know how to enable or view strain results.

ASCII Format Optistruct Superelement
When using the ASCII format for creating CMSMETH reduced stiffness and mass matrix, is it possible to represent the original structure with plotel elements (same as what happens when using MODEL = PLOTEL, ALL,RIGID command with output being H3d format)? Does anyone have an example or documentation I could follow.

Why does the holding plate move unexpectedly in CNTNLSUB, even with SPCs applied?
I have a transient nonlinear analysis in OptiStruct with two subcases to analyze (subcase 2 is a CNTNLSUB relative to subcase 1). In the first subcase, a holding plate engages with the rubber teeth to geometrically position them in their final location, having in consideration their final stress state (which is important…

45度の材料試験応力ひずみデータから、どのようにしてせん断応力とせん断ひずみの関係にしたらよいのでしょうか。
はじめに材料に異方性がある場合、0 度方向の特性なら、0度方向に揃えた材料の引張試験をして得られる、応力ーひずみの関係は、そのまま σ11 と ε11 の関係になります。 90度の場合も、90度方向に揃えた材料の引張試験をして得られた応力ーひずみの関係が、そのまま σ22ーε22 の関係になります。 しかし 45度の場合は、残念ながらそうなりません。45度に揃えた材料の引張試験を行って得られた応力ーひずみの関係は、単純に σ12-γ12 の関係になってくれません。 この部分ですが、あまり多くのコンテンツがなくて、必要なときになかなか出てこないと私自身感じていたので、本記事で、まとめとして記しておきます。…
