Whenever I go into flow simulation and either choose "Computational Domain" to edit the domain, it would become very laggy and slow. It would not hang, but would only respond after minutes. Same goes to going to results and wanting to input new "Flow Trajectories" and "Particle Studies" It would become painfully slow and I've tried it on powerful computers. It made no sense because just a week ago, I was able to do it on a MacBook Pro 13 inch.

I'll appreciate if someone is able to help out with this problem. Thank you.
