Hello Everyone,nI was trying to simulate a cyclic load analysis on steel beam column sub-assemblage but I keep getting this errorn(*** FATAL *** CP = 7935.234 TIME= 02:39:40n MPI error code = 470891279 which translates to: n Other MPI error, error stack: n MPI_Allreduce(1628)......: MPI_Allreduce(sbuf=MPI_IN_PLACE, n rbuf=000001FBD53091B0, count=292953, MPI_LONG_LONG_INT, MPI_MAX, n MPI_COMM_WORLD) failed n MPIR_Allreduce_impl(1469): fail failed n MPIR_Allreduce_intra(432): Unable to allocate 2343624 bytes of memory n for temporary buffer (probably out of memory). ) Can anyone tell me what this error is and what is causing it? And more importantly how I can remedy it? My model has 49051 nodes and 48666 Shell Elements with 24 load steps with varying sub steps per every step. An average of about 35 sub steps will be saved per every load step. I solved the model under monotonic loading and the results were correct and without error.nThanks.nn

How big is your machine? and try turning off distributed is solver options (https://ansyshelp.ansys.com/account/Secured?returnurl=/Views/Secured/corp/v201/en/wb_sim/ds_using_solve_handlers.html) and see if that helps.n-AniketnHow to access Ansys help linksnGuidelines for Posting on Ansys Learning Forumn

Aniket My PC Specs are hexacore intel core i7 2.2GHz Base Speed and 4.1GHz turbo boost speed with 16 GB DDR4 RAM and 256GB PCIe SSD Storage.n

It seems good enough to solve your problem.nHow much free RAM do you have before starting to solve?nHow much free HDD space?nand finally, did you try to run as SMP?n-AniketnHow to access Ansys help linksnGuidelines for Posting on Ansys Learning Forumn

@Aniket My Free Space was about 90GB I didn't check my free RAM I don't even know how to do that and what is SMP?nThanksn
