What should be the element size on the billet after skin?
In billet skin analysis, while examining 2 models with the same skin thickness, we noticed that the size of the first element on the billet after skin had a great effect on the results. Is there any study or suggestion by Altair on this subject? What should be the element size on the billet after skin?

How to set the container's temperature non-uniform
I am working on the container's temperature's effects on the extrusion. In order to facilitate the heat's dissipation from the billet into the environment, the container's inner face's temperature was set to be high, while the outer surface's temperature was low. How can I model the non-uniform temperature distribution in…

Time, time step and nonlinear iteration information in material UDF
Hi there. I am working on implementing a grain growth and recrystallization model into the user-defined material model. Since the model is history based, I need the time and timestep information inside of the material model. Right now I am working with fixed time steps and not using nonlinear iterations. There is a…

HX: Billet not fully consumed
Hi all, I am running a set of simulations using the same .grf file with the idea of varying parameters of temperature and ram speed. Given that the ram speed affects the simulation time - time steps at all 4 levels are adapted and the new .hx data deck is prepared in such a way. Nevertheless, if I launch the solver using…

Decoding .h3d files from Python
I have finished a simulation using HyperXtrude and obtained a .h3d file containing the model and results. I can open my .h3d file using HyperView and do the postprocessing. Nevertheless, I would like to use the .h3d file further. I want to extract data from the binary .h3d file and import it to Python. To do this, I would…

How to run HX on Linux commands (HPC)
Hi HX experts, I can run Radioss/Optistruct jobs on Linux by going to :Altair/2018/hwsolvers/scripts then type: ./Optistruct 'C:/test.fem' -nt 8. But I do not know how to run HX jobs with 2 input files: *.grf and *.hx. Could you advise? My cluster has 4 nodes (125x4 GB RAM), so I think I can run in-core solutions to get…
