[Parabolic\_integro\_eqn.pdf](https://community.freefem.org/uploads/short-url/vpnfzOQfjCQB4rejabO3COnZt3U.pdf) (121.7 KB)

Here, is my code \>  
[Integro\_Parabolic\_P1.edp](https://community.freefem.org/uploads/short-url/fxM8BupDaAVdraTgRMBk9RKV9En.edp) (3.0 KB)

Code is running fine but does not giving optimal results.

Thanks in advance!.
