  Hi, could you first try Solve Hydrostatic Only to see if there is any setting problem with the model?

  Hi, I am afraid it is hard to track the real reason for this error with few amount of information. Can you give more info about your project? Like the Ansys version you use, the size of the project, how many panels your model has, and the residual space of your disk/C: drives, did you successfully run the Aqwa project in the same file location before on your PC? Is there an ANALYSIS.VAC file in your solver file directory when this error occurs and what the file size? Is there any other error message in the ANALYSIS.LIS file and ANALYSIS.MES file?
