</font><br>
<font face="Times New Roman"><font size="2"><span style="font-size:10pt;">We are trying to compute 2-D laminar unsteady flow past a cylinder that moves perpendicularly to the mean flow direction, with the cylinder velocity being sinusoidal in time.
</span></font>We referred to the moving cylinder case in the attachment in this post:
<a href="https://lists.mcs.anl.gov/mailman/htdig/nek5000-users/2012-February/001702.html" target="_blank">
https://lists.mcs.anl.gov/mailman/htdig/nek5000-users/2012-February/001702.html</a> . We used our own mesh file and edited parameters and functions in rea and usr files according to above example.
<br>
<br>
The problem is, "makenek" exited with error. Please find in attachment the file "compiler.out". The last part of the info are:
