Default Reinitialization for level set method

Hello

I want to track the front of gaseous detonation by level set method.

What is the necessity of reinitialization in level set method? why do I use this tecnique?

Is it just for brevity in equations? In other word, is it just for omitting [grad(phi)] in equations? Is it realy necessary?

regards.

It is neccesary to initialize the level set function. Due to numerical diffusion during advection of level set field, it will be smeared and so will not be at its actual position. You need to reinitializase to correct this problem
