Hello,<br>
<br>
Thank you all for your help.<br>
<br>
I have changed VecGetArray to VecGetArrayF90, and the location of destory call. but I want to make sure that VecGet ArrayF90 is to make a new array( vector) that I can use in the rest of my Fortran code?<br>

</div>
This is not the correct calling sequence for VecGetArray() from Fortran. </div>
<div><br>
</div>
<div> Regardless, definitely should not be writing any new code that uses VecGetArray() from Fortran. Should use VecGetArrayF90().</div>

<div dir="ltr">This is a segv. As Matt said, you need to use a debugger for this or add print statements to narrow down the place where this happens.
<div><br>
</div>
<div>You will need to learn how to use debuggers to do your project so you might as well start now.</div>
<div><br>
</div>
<div>If you have a machine with a GUI debugger that is easier but command line debuggers are good to learn anyway.</div>
<div><br>

<div>I tend to run debuggers directly (eg, lldb ./a.out -- program-args ...) and use a GUI debugger (eg, Totalview or DDT) if available.</div>
