Hi Marco,
<div><br>
</div>
<div>It looks to me like you're trying to overwrite a constant in interp_vt().</div>
<div><br>
</div>
<div>I see the following:</div>
<div><br>
</div>
<div>
<p style="margin-right: 0px; margin-left: 0px; line-height: normal; font-family: Courier;">
call interp_vt(ih_rbc,uvwt,xyz,npts,.false.) ! interpolation</p>
<p style="margin-right: 0px; margin-left: 0px; line-height: normal; font-family: Courier;">
:</p>
<p style="margin-right: 0px; margin-left: 0px; line-height: normal; font-family: Courier;">
:</p>
<p style="margin-right: 0px; margin-left: 0px; line-height: normal; font-family: Courier;">
:</p>
<p style="margin-right: 0px; margin-left: 0px; line-height: normal; font-family: Courier;">
subroutine interp_vt(ihandle,uvwt,xyz,n,iftmp)</p>
<p style="margin-right: 0px; margin-left: 0px; line-height: normal; font-family: Courier;">
:</p>
<p style="margin-right: 0px; margin-left: 0px; line-height: normal; font-family: Courier;">
:</p>
<p style="margin-right: 0px; margin-left: 0px; line-height: normal; font-family: Courier;">
iftmp = .false. ! no temperature</p>
</div>
<div><br>
</div>
<div><br>
</div>
<div>which is trying to overwrite ".false." ... ?</div>
<div><br>
</div>
<div>Please let me know if this resolves your issue.</div>
<div><br>
</div>
<div>Also, I see in your SIZE file that lelt=10000. Are you running only on one processor?</div>
<div>If the number of elements in your .rea file is ~10,000 and you are running on (say) 1024</div>
<div>MPI ranks, then you only need lelt=10. Resetting lelt and lelv in this way would result</div>
<div>in a significant reduction in memory footprint and possible increase in performance.</div>
<div><br>
</div>
<div>Best, Paul</div>

<div class="PlainText">Hello,<br>
<br>
I have a subroutine that interpolates the velocity for a list of points and have a strange error message when I try to run it. It seems that the variables ‘nx1’, ‘ny1’ and nz1’ are not defined even though ‘SIZE’ is included in the subroutine. As far I understand,
the variables ‘nx1’, ‘ny1’ and 'nz1’ are made available in a subroutine by simply including ‘SIZE’ at the beginning. I attached the case to reproduce the error message that is:<br>
<br>
Access to an undefined portion of a memory object.<br>
<br>
Any help would be appreciated.<br>
<br>
