Dear Nadeem
1 - Relative Tolerance is the convergence criteria value in COMSOL. The default value is 0.01 in COMSOL. If our study involves solving multiple equations, the value given here will be taken as default for all the equations. What is the problem you are facing here ?
2 - First solve the initial problem with Study 1. Create a new study (say Study 2). Under the new study, there is a node named "Values of Dependent Variables". Under that there is "Initial values of variables solved for". Select Study 1 there. So the outputs of Study 1 will be the inputs of Study 2.
Hope it helped you.
I have got it through my colleague. We can set it under Study --> Relative Tolerance
Hello Hakeem Niyas,
Can you please help me to set this "Relative Error". Because, I am also facing same problem but did not solved by changing it. Or any idea how to use the "Previous solution" as initial value for new analysis, for the sake of solution convergence??

Dear Hakeem,
Just as in the attachment to set the "relative tolerance".
