How to simulate the water boiling by Level-Set method

There is a good example simulating water boiling by phase field. I am trying to use the Level-Set method. However, I was frustrated by many times of failure. My problem is how to deal with the...

Re: How to simulate the water boiling by Level-Set method

Hi Junxiang. did you manage to solve the problem? I am stuck with the same issue. I really cannot figure out the concept of weak form, and I don't know how should I change the source term if I want to...

Re: How to simulate the water boiling by Level-Set method

Nope, I am still stuck on this problem. I tried to get the source term according my understanding of Weak Form. But I failed. Weak form is powerful, but not easy to use. :( I have another problem on...

Re: How to simulate the water boiling by Level-Set method

I did some modeling on homogeneous ice nucleation and also fluid evaporation. I agree that it is a little bit hard to do that in COMSOL, but it is possible after some simplifications. I need to know...

Re: How to simulate the water boiling by Level-Set method

Hello, I am in the same situation Junxiang was in originally. I am reading up on both phase field and level set theory to try and reformulate the boiling water problem and run it using the Level Set...

Re: How to simulate the water boiling by Level-Set method

Hi I had exactly the same problem than you, I mean, I couldn´t understand why they used these test functions in particular. I contacted with the support service and they helped me with this. If you...

Re: How to simulate the water boiling by Level-Set method

Hi , This might be stupid question but could anyone help me to evaluate Delta interface function for level set with expression just as how it was described for phase field in boiling water example...
