Plot stress in the ply direction (Radioss + HyperView 2025)
Hello, I created a simple Radioss 2025 model of a composite cube with the P6_SOL_ORTH property. After opening the .h3d, it is impossible to plot the stress in the composite orientation (Ply system) with HyperView 2025 : I have the following parameters in the 0001.rad file : /H3D/DT 0.0 0.001 /H3D/ELEM/TENS/STRESS…

HV SETS automation for HyperView TCL/HWC scripting.
My point of reference is for Nastran Bulks and OP2. Situation For example if you have defined a Element set "set_cs" in the case control section in the master bulk with an ID =6. Once the model and results are loaded in the HyperView, you'll see first 5 sets automatically created. #Name Type ID 0D Set Components 1 1D Set…

In the HyperView post-processing interface, the Contour display shows "No Result" and the Result typ
When I used MotionView for the coupling of rigid and flexible components, after the simulation was completed, I used HyperView to view the relevant forces. However, in the post-processing interface of HyperView, there was a situation where the Contour (cloud map) displayed "No Result" and the Result type was empty. I don't…

Stress range visulation
Hi everyone, I want to calculate stress range in fatigue load cases. Fatigue is a cyclic stress and we have 3 layers i.e., Z1, mid and Z2. When I use range in envelope of LC1 and LC2, where LC1 and LC2 are stress cycle, the value get is range = max(Z1, mid, Z2)-min(Z1, mid, Z2). But what I want is Range 1 = max(Z1 of LC1,…

.h3d file and .force file correlation
Hi, I just wanted to confirm exactly what results the .force file presented compared to visualising the results in a .h3d via Hyperview? For example, I was under the impression that if you gave an element a defined MCID that this is what the .force output file would generate results with respect to. However, when I check…
