## Error Messages

1193: Maximum number of linear iterations reached

An error "Maximum number of linear iterations reached" occurs. If you get this error, the iterative linear system solver did not converge due to a bad initial guess or a bad preconditioner. To avoid the error, increase...

1192: Initial guess leads to undefined function value

An error "Initial guess leads to undefined function value" occurs. 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...

1191: Segregated solver steps do not involve all components

An error "Segregated solver steps do not involve all components" occurs. The groups for the segregated solver do not include all dependent variables. One reason for this error could be that some boundary conditions...

1190: Fatal error

A "Fatal error" occurs. If you receive this error, copy and paste the entire error message and send it to support@comsol.com along with...

1189: Unsupported integration order

The error "Unsupported integration order" occurs. The integration order for the numerical quadrature is too high. For triangular elements the order can be up to 10, and for tetrahedral elements the order can be up to...

1188: Internal evaluation error: unexpected NaN encountered

The error "Internal evaluation error: unexpected NaN encountered" occurs. This error occurs when Not-a-Number (NaN) values appear unexpectedly. Such values can be the result of floating-point operations such as 0/0,...

1187: Undefined function call

The error "Undefined function call" occurs. An expression in the model contains an undefined function name. Check that the function name is correct and that the function is in the COMSOL Multiphysics or MATLAB®...

1186: Out of memory during assembly

The error "Out of memory during assembly" occurs. This error message indicates that your computer does not have enough RAM memory to assemble the numerical model which you are working with. There are two distinct,...

1184: Duplicate parameter/variable name

The error "Duplicate parameter/variable name" occurs. A parameter name or a variable name has at least two different definitions. For instance, the same variable name appears two or more times for a dependent variable,...

1183: Wrong number of DOFs in linearization point

The error "Wrong number of DOFs in linearization point" occurs. The current solution or the stored solution has for some reason the wrong number of degrees of freedom, sometimes due to a change of the implementation of...
