Die velocity as a variable in Hyperstudy

Hello,

I am trying to perform optimization of a parameter in forming process. I performed a forming analysis in Hyperform using Incremental radioss solver. Then I used this .rad file in order to setup a study in Hyperstudy. I want to use Die velocity as a variable for the optimization study which is shown in the figure below-

I created a parameter for the Die Velocity in Hyperstudy from the .rad file as shown below-

Then I performed a nominal run where the setup was run for the current, upper and lower limit value of the created Die Velocity parameter. Hyperstudy ran successfully for the current value of Die velocity, then it changed the value from -5000 to -6000 as expected in the .rad file generated for the next run but did not complete the run for a very long time. I had to stop the run.

I do not understand how I can use Die velocity as a parameter in the Optimization setup in Hyperstudy. Kindly help me with this difficulty.

Thank-you in advance for your help!

Hello,

As I mentioned in the last post, I want to change the die travel velocity and study its effect on the quality of a formed part. I understand that I need to use a parameterized file model to setup a study in Hyperstudy. I tried to parameterize the velocity (-5000 as can be seen in figure above) and did just a nominal run taking velocity as -6000. The changed value appeared in the .rad file generated for the nominal run but the run did not progress after about 14 animation files were written.

I am not sure if my approach is right. Do I need to write any templex statements in order to make this work? Do I need to replace the values of the IMP_curve-die.1 (please see figure above) using templex statements?

I really need to understand this. Kindly help me by giving your valuable guidance and suggestions.

Thank-you in advance for your help!

It would be nice if you can share final .rad files(Radioss)/.hstx file(HyperStudy) of the run. Also please let us know which version of Radioss and HyperStudy you are using.

Hello Rahul,

Thank-you for your response. I could parameterize the die velocity by writing some templex statements in the .rad file imported in the Editor in Hyperstudy. I am attaching a picture of the templex statements written to generate the velocity-time function

The picture on the right shows the templex statements written in order to make changes in the curve shown in the picture on the left.

I am using Radioss and Hyperstudy version 2017.1. Since I could solve the query, I am not attaching the .rad file here.

But I had another question about Hyperstudy. I want to add two models to Hyperstudy. Both have RADIOSS as solver. I want to use parameters from the first model as inputs and optimize a parameter from the second model. Can this be done? I have not yet setup these models in Hyperstudy so I don't have any files to attach. Kindly let me know if this can be done.

Thank-you for your help in advance!

Glad to know that you self rectified first query.For second query i think it is possible to load two models.Starting from 2017 version we have one feature called Model Resource in HyperStudy which should work in your case.Please refer attached video for Model Resource.
