Hi,
I am new to Simscale and am currently trying to model a dynamic impact test of a portable charger I have designed . I have imported the charger and rectangle shape to mimic the ground that it would be impacting with.
When I try and create the mesh I keep getting this error,
‘A fatal IO (Input/Output) error has occurred while the mesh or the simulation was running.’
Any help would be greatly appreciated as I have no idea why this isn’t working.
Hey there, and welcome to the forum!
Thanks for making use of this great resource.
I just had a look at your model and found some interference between the screws and the back cover:
The model should not have any interference, this way the meshing algorithm can work correctly.
Also, I would suggest you to simplify those screws, for example:
You could also reduce the ‘floor’ size to save on mesh size and computation time.
Please let me know if this helped!
Hi,
Thanks a lot for the reply, it seems like the problem is still happening. I removed the screws and made the ground smaller. Unsure what to do next?

Hi @wardencalum,
From the meshing log, the issue is that the maximum precision of the model is very high (greater than the small feature suppression currently applied):
A quick way out here is to define a larger value for the small feature suppression (e.g. 1e-4):
Cheers
Hi,
That has worked for the mesh, thanks!
Only problem now is that when I go into the post-processing animation it is not animating the two parts actually colliding. Also if I want to see the stresses over the whole body when they collide do I have to select the whole body as the physical contact?
