Cody: she should be able to use the "ghosted_boundaries" option in the Mesh block to specify boundary IDs of elements that should be fully ghosted to all processors... that should enable contact to work. Derek On Thu, Mar 9, 2017 at 11:16 AM Cody Permann wrote: > Roy, before we spend a lot of t

Roy, before we spend a lot of time going doing the debugging path, I can point you right to the general problem. She mentioned that this is for a "contact" problem. In MOOSE that means two disjoint meshes are going to be pushed together and our contact system handles that by taking a list of bounda

Yeah, I thought so. I believe I've seen a few of your threads on the libMesh list. I can tell you that I've personally run into that assertion on my own larger problems as well which has prevented me from running my largest simulations with DistributedMesh myself. I will say that contact definitel

Hi, concerning the repository, we have a private repository and i am running solid mechanics simulations with contact. But the error appears before starting to solve the problem. thus i do not think that it depends on the problem i am running. Let me know if i have to provide other details or if

Hi, actually this was just a test and i really need to use distributed mesh for my problem. Moreover I am using the last moose version. Best Maria > On 09 Mar 2017, at 16:06, Cody Permann wrote: > > Hi Maria, > > We are slowly working our way towards supporting distributed mesh in the > fra

Hi Maria, We are slowly working our way towards supporting distributed mesh in the framework at a more "first class" level. There's a lot of active development in this area right now to patch up problems. Many things work, but there are still many more that do not work with distributed mesh at thi

Dear all, i am trying to run a simulation in the MOOSE framework which is based on Libmesh. I am trying to use distribute mesh, but when i run in parallel i in debug mode i get the following assertion: Title: cubit(/Users/studi/src/cgp/meshes/signorini/hemisphere_5191.e): 03/07/2017: 09:2 Mes
