Hello everyone,I'm trying a modal acoustic simulation, but when I run the solution this unknown error happen:nAn unknown error occurred during solution. Check the solver output on the solution information object for possible causes.nCan anyone would help me with that?n

,search for I/O (or i/o) inside the solver output file. Share the picture here if it is present inside the solver output file.n

,which ANSYS version are you using? What is the RAM and number of cores in your computer? nIn 2020R and above, on the Home tab, untick the 'distributed' option.nIn below versions, goto Tools, Solver output settings, advanced, and then untick the 'distributed Solution' option.nThe distributed solution actually requires a greater use of RAM which may disrupt the solution progress. Since there are are no other errors in your solver output file, I am guessing this is the problem.n

Array, thanks for helping out! Array, do you see any erros in the solver output? I don't see any error in the output that you have shared. Maybe you should check:nC:\Users\Leone\AppData\Local\Temp\WB_LAPTOP-R4A1Q9LI_Leone_1496_7\_ProjectScratch\ScrF398\file0.err for the error message.n-AniketnHow to access Ansys help linksnGuidelines for Posting on Ansys Learning Forumn

the version that I'm using is Academic 2020 R2. My computer is a i5, 8GB RAM.nI tried untick the 'distribuited', but now a other error happen: n*** ERROR *** CP = 6221.281 n An unexpected error ( SIG$SEGV ) has occurred... ANSYS internal data n has been corrupted. ANSYS is unable to recover and will terminate. n Previously saved files are unaffected. Please send the data leading n to this operation to your technical support provider, as this will n allow ANSYS, Inc to improve the program. n

,how many cores have you dedicated to the solver? Check the number of cores your computer has, and then check if the analysis is running by changing the number of cores (in the Home tab on ANSYS) to 2, for example.nIf the problem is still not solved, apply many more of fixed supports to different locations within the model, to check if rigid body motion was causing this problem.n
