Dear all,
I am simlating numerical wave tank in COMSOL 5.4. I do my simulation with Twophase_Flow ,Phase Field & Moving Mesh.
I worked 2 models. Model 1 is 30 meters width & 5 meters height. Model 2 is 500 millimeters width & 200 millimeters height. Also, I define the waveform and step functions in definitons to simulate the wave maker. I confused that I changed angular frequency in the waveform function, and give times that range (0,0.1,10), the result is not converged. the study of ‘Time Dependent’ just converge from 0 to 1 second, but cannot converge from 0 to 10 second. Model 2 has no problem. Maybe the reasons are the followings: 1. The definition of waveform or step function, 2. The definition of Laminar Flow/ Phase Field. So what can I do to optimize my models and work out the problems.
Regards
Joey
