Error: out of memory (works with version 2018)

[Priyesh Kakka]

Hello,

I am trying to simulate a code which was written by a senior few years back. I have installed a conda version fenics-dolfin v2019.1.0 in a cluster node(256 GB ram). When I try to run the following code with ngx and ngy set to 128, it throws an error "for out of memory". I tried it with 32 and 64, and it works but is too slow. 

The senior of mine had installed the package with v2018.1.0, and for him with 128 mesh size, the code works well and is way faster. Can you please let me know a way to install v2018.1.0 in the conda environment? Also, there might some issue with the current version?

I am particularly interested in the dolfin package.
