hello,

I use the comsol multiphysics 3.5a

I am having difficulty comsol to converge on time dependent solutions.

Recently i happened the error i can not understand

Error:
Failed to find consistent initial valuses.
Last time step is not converged.

I have attached the model file and some of fictures.
please check the my model file.

first I succesed the transient initialization of two phase flow, phase field

then i tried to transient but happened the error

on the fifth line from the top of the message.

So i thick that i had not defined enough variables, and incorrect geometry, boundary conditions

I checked theirs but did not find out error factors.

please check the my model file.



I have one more question.

iI take a fluid load on the solid part at the boundary settings of plane strain

but fluid load unit is red on the Load tab

why unit(N/m^2) shows red at the Load tab

Please help me

Also, which method will be best?
Help will be most appreciated,

I will wait for you.
