EDEM/Motionsolve Coupling - Failed to export geometries to EDEM
Hi,
I want to couple motion solve with EDEM to test how my robot moves in sandy terrain. I have followed the tutorials of creating my EDEM simulation (which works on its own) and motionsolve (also works on its own). From there I have followed the following steps:
1. Run EDEM Simulation
2. Save simulation deck from analyst from timestep 0
3. Open simulation deck and start coupling server
4. Go to motionsolve -> assembly -> EDEM
5. Select graphics (in my case my wheels/pedallers, see attached photo)
6. Transfer and Create System
From there, I get the following errors
"14:59:23" "ERROR" "MotionView" "No valid EDEM installation found. [General]"
"14:59:32" "INFO" "MotionView" " 2. Verify that no older EDEM paths have been left in the PATH directory. [General]"
"14:59:32" "INFO" "MotionView" " 3. If (1) + (2) fail, add EDEM path at the highest possible position in the PATH [General]"
"14:59:32" "ERROR" "MotionView" "Failed to export geometries to EDEM [General]"
"14:59:23" "INFO" "MotionView" "Please make sure sure EDEM is installed in the current HW installation directory [General]"
"14:59:32" "ERROR" "MotionView" "Import of EDEM module failed, cannot locate 'EDEMCouplingClient4.dll' or the EDEM version is not compatible with the HW version [General]"
"14:59:32" "INFO" "MotionView" "To resolve the missing EDEM module problem, please: [General]"
"14:59:32" "INFO" "MotionView" " 1. Make sure EDEM/hwsolvers are installed in the current HW installation directory [General]"
I then uninstalled my 2022.3 EDEM and reinstalled 2023 EDEM to match my Hyperworks version 2023. So my current program folder structure is as follows:
C:\Program Files\Altair\2023\EDEM\bin
C:\Program Files\Altair\2023\hwsolvers\motionsolve\bin
I have added the following lines to the top of my path in environment variables and restarted my machine:
C:\Program Files\Altair\2023\hwsolvers\motionsolve\bin
C:\Program Files\Altair\2023\hwsolvers\motionsolve\lib
However still the same error.
Any advice would be much appreciated
Kind regards,
Gaetan

- Have you installed HyperWorks and EDEM under the same install ? Could you please show how your install folder looks like. (e.g. C:/Program Files/Altair/2023). you should see hwdesktop and EDEM folder underneath there in case you install both of these together.
- you mention, you followed the tutorial. were you successful in running through the tutorial ?
- If these are installed separately, you need to put the path of EDEM/bin and EDEM/lib in the path. not of motionsolve.

Hi Praful,
I got it fixed but uninstalling everything and reinstalling it using the hyperworks package installer. Turns out I was missing Altair desktop.
Thanks
Hi,
I want to couple Optistruct with EDEM by using Altair simlab2025, ( for EDEM i'm using Altair EDEM 2023). I follow all the process for the tutorial video but when i run the coupling process the geometry design in simlab doesn't appear in EDEM.
also i would like to give the simlab design a rotary motion but i don't really know how to do it.
