[EDEM] Can we get energy loss with GPU calcuration

Sakae

Hi,

I'd like to get energy loss after simulation by GPU.

I think currrent .dill file that we use for getting energy loss is available only CPU calculation. Do you have any idea to get it with GPU calculation.

Hi,

We are currently developing an Energy loss model to work internally with EDEM, however this is not completed yet.

The API model here runs on CPU only:

EDEM API - Contact Model Example: Energy Loss

However it has recently been updated to run on GPU. To use you need either the .dll (Windows) or .so (Linux) and the .cu file (for GPU) in the same location as the .dem file, otherwise follow the same instructions to use as in the above post.

EnergyLossGPU.zip

We will update the post with the model shortly.

This is different to the model which is to be released with EDEM 2025.x (or later) which will have more functionality.

Hi, thank you for your quick reply.

I have tried to use it but it seems not to work.

Please refer to below. My operation is correct?

Hi Sakae, It looks like the Linux version was updated but not the windows one. The engineer who updated the model is on vacation and back on Monday, we'll attach the updated version then.

Hi, could you send me Windows version?

Thank you for your support

Hi Sakae,

Here's the Windows version of the Energy Loss API

Thank for your support.

I have tried to use it , then it have worked well.

But I wonder the result with my past calcuration by CPU and my

EnergyLoss_CPU.dll

EnergyLoss_GPU.dll

new calculation by GPU is totally different. Why it happend, is there any idea?
