来自COMSOL的Error Messages,希望对你有用
7043 Initial guess leads to undefined function value        This error message usually appears when you have set up an expression that returns “not a value,” that is, it is undefined, for the initial condition you have set. For instance, this happens if an expression contains a divisor that becomes zero or a logarithm of a negative value. To solve the problem, change the expression or the initial value so that the expression is well-defined when substituting the initial value of the variables. Also, watch out for warnings in the Log window.
7248        Undefined value found        See the explanation of error 7043 for some possible reasons as to why this error number appears. In most situations you get a more detailed description of the error by pressing the Details button.
7297        Undefined value found        This error number appears if one of the linear system solvers encounters an undefined value (such values appear, for instance, if a division by zero has been performed or if some arithmetic operation results in a larger number than can be represented by the computer). For direct solvers this error might appear if the stiffness matrix (Jacobian matrix) is singular or almost singular. For iterative solvers this error might appear, for instance, if the iterative process diverges. Press the Details button to see which linear solver caused the error.

暂时没有好办法,如果是多物理场耦合,建议一个一个的添加。这样如果出错容易找一些。
