How to set up multiple impact/load/velocity scenarios for simulation in Radioss using Hypermesh (parameters??)?
Hi,
I am attempting to simulate the impact between a plate and a block at different speeds but am struggling with understanding parameters/load steps/etc. So far, I have created the proper file in HyperMesh and successfully simulated impact (with results), but I am curious about how I should approach simulating a variety of impact velocities (i.e. the plate at a variety of initial velocities just prior to impact with the block) without simply simulating it at one initial velocity, and then editing the file in HyperMesh to simulate it with another initial velocity before finally attempting to combine the data to analyze how the results change (as this is quite a time consuming task and I would benefit from being able to set up multiple scenarios and let the computer run and process overnight). Is there a way to make use of parameters or other features in HyperMesh (for Radioss) to simulate multiple impact scenarios at different initial velocities all in one go?
Please let me know if you require any clarification.

Hi,
once you have created these parameters in HM, you can call HyperStudy and setup a variation study using this parameter as design variable.
It could be a simple DOE for varying your parameter and measure some value, or it could be an optimization, if you have a target.
Another option, more manual, if you only need to run multiple models, you can export multiple files from HM, by changing these parameters, and just run them into the RADIOSS job launcher, as they will go to a queue.
Thank you! I was able to create a simple DOE in HyperStudy to vary the parameter and run multiple instances of the same model
Hi
In Radioss you can use /PARAMETER as well.
so that you can define it and use on the scale field of /INIVEL for instance.
And as Adriano has mentioned, you can change the value set on /PARAMETER with HyperStudy help.
