Hi @oseyemiayobami,
the failure reason is mentioned in the run event log:

So basically the mesh is too big for the number of cores (and implicitly the RAM attached to them) you selected, it has 3.4 million (!) nodes, and you selected only 4 cores:

With a free account you will likely not be able to solve such large problems, as that is limited to 16-core machines.

Anyways, I would suggest to start with a 1st order mesh and try to solve that one first as this allows to iterate over your trials faster - you might also have some other issues to tackle (e.g. your boundary conditions seem odd).

Best,
Richard
