<p class="MsoNormal">Hello,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I have written a code to solve a simple differential equation (x’’+x’+6x=0 with initial values, x(0)=2, x’(0)=3). It works well on a single core and produces result close to theoretical answer but whenever I am trying to run the same code
on multiple cores, I am getting incorrect results. It seems to me that, for multiple cores it stops after taking only 2 steps regardless of the final time and gives the final result (which is inaccurate). I tried different TSType (TSEULER, TSBEULER, TSSUNDIALS,
TSCN etc.) but I always ended up with the same issue.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Can you tell me what possibly may cause this problem? Thanks in advance.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
