I saved the results&nbsp;named &#8220;ts-001.cdat&#8221;, &#8220;ts-002.cdat&#8221;, and so on. After the simulation, I closed the saved case-file. Now I want to continue this simulation from 1s to maybe 2s. If I open the transient case-file once again and initialize with the last timestep-number 100, it starts with a current time of 0s.<\/p>\n<p><\/p>\n<p>So, how to change the starting current time to maybe 1s and how to write the result-files starting with &#8220;ts-101.cdat&#8221; and not with &#8220;ts-001.cdat&#8221;?<br \/>This should make it as if I had the simulation run from 0s to 2s from the beginning.
