writing variables in hyperstudy didn't work only when using GPU

Hello, I'm sorry to asking again this problem.

I checked the GPU problem, but solver alaways worked well only used EDEM or for test model, and with only solve with CPU the variables bound in hyperstudy writed well.

but when EDEM solver use Gpu, hyperstudy couldn't write changed variables .

In hyperstudy UI variables changed, but when I checked the result and open the EDEM, the variables(ex, initial velocity, accelation) didn't changed

I checked input variables and preference and link, etc.. but only difference is just checked EDEM solver engine CPU to cuda solver.

How can I solve this problem?

I'm using 2022.2 verstion now.

Thank you for your interesting.

Byun.

    Hi,

    The solver shouldn't have any influence on writing the files, if the simulation is run with CPU or GPU it runs from the same simulation.

    You can check by just writing the simulation files in Hyperstudy rather than Executing just Write the files and open to check if the variables have been written, a log file should be provided if it fails to write to the file.

    It may also be good to update to the latest 2024.1 version.

    Regards

    Stephen
