Hi Nek,<br>
<br>
Is there anyone knows how to calculate the curvature in .rea file.<br>
Recently, I want to generate a pipe mesh but it doesn't seem like a pipe in<br>
which I guess there is something wrong in curvature part in .rea file. I<br>
have attached the mesh part below.<br>

Dear ZJ,<br>
<br>
<br>
In order to parse the characters in the line, nek uses formatted reads for<br>
<br>
curve sides and for BC info.<br>
<br>
<br>
The format changes as the number of elements increases in order to accommodate the larger integers (i.e., the element number) in the same line,<br>
<br>
so you have to check either the reader source or prenek source or a valid<br>
<br>
.rea file to see what that formatting looks like.<br>
<br>
<br>
I've fixed your pipe mesh here. Note that there is a 2D pipe mesh (but with a different base template) in NekExamples/pipe/w2dcyl020a.<wbr>rea<br>
<br>
<br>

Hi Nek,<br>
<br>
Do you know what can I do for the pipe running. It was good before, but I<br>
dont know why it doesn't work now it shows the error below when using<br>
nekmpi. I re-genmap even re-generated the rea file which didn't work.<br>
