After doing the analysis the structural result file is taking too much hard disk space. Actually I am interested in the result of the final step. I am using MAPDL. Can any one help me out to avoid the results in the intermediate step to be avoided?
If you have many loadsteps, then enter "outres, all, none" before solving all loadsteps except the last. Previous to the last loadstep, enter "outres, all, last".
Why bother? The intermediate data is so crucial that you can trace the nonlinear behavior to see how your simulation goes wrong. What you need is to make the code deliver the intermediate results "less frequently".
If you don't need to see the history, but only need the most recent results to restart the program, you may "rewind" to the beginning of the file and overwrite it with the most recent results.
