Edit Topology on Midsurfaces and Solids
I am searching for a way to edit topology in Hypermesh. The edit Topology Tools in V2026 (Split and Quick Edit) seem to work for specific problems, but when editing problematic surafaces / edges or solids they tend to be at their limits. I am therefore wondering, if it is possible to edit topology in the following ways :…

Is there a way to rapidly correct a bad mesh?
I was simulating a part where a imprinted 2d elements between two components (fist and second photo) and one of the meshs presented bad elements after I imprinted them (third photo). I'm using the "replace" tool in the edit elements function of the 2d tab, but it takes a long time to correct this, is there a faster way to…

2D Acoustic Simulations Possible
Hello, I want to perform 2D acoustic simulations, only acoustic pressure as DoF and no fluid-structure interaction. Furthermore, I want to simulate an open boundary, that means I need CACINF or CACPML elements. As far as I understand their description, these elements are only available as 2D elements suitable for 3D…

How to imprint a surface mesh from a pressed assembly
I have a surface mesh on a component that is pressed against another surface. I would like to avoid creating contacts between these two parts and want the mesh to be imprinted onto the unmeshed surface. When I try this with imprint it cannot fulfill my aim as the unmeshed geometry is a CAD file. What are some workarounds…

Is there any OptiStruct shell formulation (PSHELL, PCOMP, PCOMPG, etc.) that supports surface-locate
I'm trying to understand whether it is possible in OptiStruct to place shell-element through-thickness integration points directly on the shell surfaces, similar to how ANSYS SHELL181 uses Simpson integration through the thickness. For a standard PSHELL/CQUAD4 model in OptiStruct, the through-thickness integration points…

How to automatically improve elements failing min size criteria
I have generated my 2D tetra shell mesh which is of relatively good quality in terms of skew, aspect ratio and jacobian. I have 99 elements that would not meet my minimum size requirements and have also selected their adjacent elements. Below is just a few of them I get an error by rebuild that a size (0.16) conflicts with…

Hyperlaminate, Laminate PCOMPP Free Size Optimisation Problems
I'm having some issues performing a free size optimisation on a monocoque I'm designing in my spare time. I have made a working laminate structure using Hyperlaminate, this effectively places my laminate directly into the PCOMPP Property card, which is perfect when performing a simple analysis. However when I got around to…

Composite tennis racket in Radioss
Hi everyone, I am currently working on modeling a composite tennis racket to simulate the impact of the ball with the racket strings. I have a few doubts regarding the simulation of the strings: should I represent them using 1D beam elements ? Also, what type of contact should I implement between the strings? Would an…

LS-Dyna solver - Strain Energy Output
Hello, I am using LS-DYNA solver for a windshield impact simulation. The glass is modeled with *MAT_ELASTIC and failure is defined using *MAT_ADD_EROSION with critical stress, critical energy and critical radius values. In HyperGraph I can only see MATSUM internal energy, but this is the internal energy of the whole…

Pretension analysis
Hii everyone, I have this confusion. I performed pretension analysis in a bolted joint. The bolt is modelled as 1D Beam element, a 18kN Pretension force is applied. The thing is when I simulate that, the displacement and stress are 1500 mm and 1000 MPa, the components joined together by the bolt, went directly inside into…

how to save & retrieve bad elements
Hi, When I display the 3D elements quality, I'm noticing elements with a negative jacobian, but i cannot see them on the mesh (of course I played with the cursor on the legend). In the past, with the old interface, it was possible to reccord & retrieve those bad elements, but I not able to reproduce it: how to proceed?…
