Title: Solving time dependent problem in Parallel (SunGrid)
Post by: abbhuiya on May 19, 2014, 01:46:20 PM

Dear Sir,

I have been using the following commands to solve a time dependent problem in parallel feap (single processor, SunGrid).

BATCh
 PROP
 DT,,1
 END
 
 BATCh
! DIREct,BLOCk
!DIREct,BLOCk,40000000
 DIREct,SPARse
 TANG
 LOOP,time,          10
 TIME
 FORM
 SOLVE
 NEXT,time
 END
 STOP

When I checked the Ofeap file, I didn't find any results for the commands TANG, LOOP, TIME, FORM, SOLVE, etc....... I have attached the ofeap file as well.  What am I doing wrong? I could solve time independent problem successfully. Is there any special instruction for time dependent problem?

Best Regards

(1) do not use direct sparse (this is only for FEAPs built-in solvers)
(2) you need to execute with mpirun/mpiexec if you want to be using "parallel" PETSc solvers
(3) you need to turn on PETSc
(4) You need to create your input file using 'GRAPh,NODE,1' + 'OUTDomains'
