GSP and Cyclic Boundaries

Hello,

I was playing around with the fb_gsp tutorial today and noticed that using cyclic boundaries yields the error

From: DESMPI_UNPACK_PARCROSS:

Error 1000: Unable to match particles crossing processor boundaries.

Source Proc: 0 ---> Destination Proc: 0

Global Particle ID: 819

Initially, I thought that this might have been the usual time step resolution issue, but increasing the particle stiffness by a couple orders of magnitude gives the same result.

Is this a known issue with GSP?

Thank you!

-P

This looks like a bug.
Thanks for pointing it out. We’ll work on a fix.

The implicit GSP model is fine, the issue is with the explicit model.
