Dear all,
When I simulate the generation, growth and rupture of bubbles, the calculated bubble of the system grows to a certain degree, the system always expands to a large extent, and it cannot go on, showing ERROR: Non-numeric pressure-simulation unstable (…/fix_nh .cpp: 1045)
How should I solve this problem, thank you
