All error messages are numbered and sorted in different categories according to the following table.TABLE 2-1: ERROR MESSAGE CATEGORIESNUMBERSCATEGORY1000–1999Importing Models2000–2999 Geometry Modeling3000–3999 CAD Import4000–4999 Mesh Generation5000–5999 Point， Edge, Boundary， and Subdomain Specification6000–6999 Assembly and Extended Mesh7000–7999 Solvers8000–8999 Postprocessing9000–9999 GeneralFor error messages that do not appear in the following lists, contact COMSOL’s support team for help.2000–2999 Geometry Modeling?TABLE 2-2: GEOMETRY MODELING ERROR MESSAGESERROR NUMBERERROR MESSAGEEXPLANATION2118Negative output from empty inputIncorrect Geometry M—file.2119Non scalar output from empty inputIncorrect Geometry M-file。

2120Normal directions are inconsistentIncorrect input data from STL/VRML import.2138Self intersections not supportedCurves resulting in self—intersections are not supported2140Singular extrusions not supportedError in input parameters2141Singular revolutions not supportedThe revolved mesh has a singularity at the z axis. If possible, create the cylinder using a 3D primitive or by revolving the geometry before meshing2146Subdomain must bounded at least four boundary segmentsIncorrect geometry for mapped mesh。

2147Subdomain must bound one connected edge component onlyIncorrect geometry for mapped mesh2190Invalid radius or distanceIncorrect input parameters to fillet/chamfer.2197Operation resulted in empty geometry objectGeometry operation resulted in an empty geometry object which is not allowed. Make sure an empty geometry object is not created2209Geometry to revolve may not cross axis of revolutionThe axis of revolution and the geometry intersect. Check the dimension of the geometry and the definition of the axis for the revolution。

?4000–4999 Mesh Generation?TABLE 2—3: MESH GENERATION ERROR MESSAGESERROR NUMBERERROR MESSAGEEXPLANATION4002A degenerated tetrahedron was createdThe mesh generator ran into numerical difficulties while creating tetrahedrons with a size based on user-controlled parameters. Causes could be too small and narrow subdomains relative to the rest of the geometry or exceedingly short boundary segments. Try to avoid creating small and narrow subdomains and very short boundary segments that are adjacent to longer boundary segments.4003A degenerated triangle was created The mesh generator ran into numerical difficulties while creating triangles with a size based on user—controlled parameters. Causes could be too small and narrow subdomains relative to the rest of the geometry or exceedingly short boundary segments. Try to avoid creating small and narrow subdomains and very short boundary segments that are adjacent to longer boundary segments.4012Cannot create mapped mesh for this geometryThe geometry does not fulfill the topological requirements for a mapped mesh。

Changes in input parameters or further subdomain division can possibly help this4026Failed create matching edge discretizationsCannot make mapped mesh with the given input parameters4029Failed to insert pointProblems inserting point at given coordinate. Manually inserting a point there may help4031Failed to respect boundary element on geometry edgeThe mesh generator failed in making the elements compatible with the geometry object's edges The reason for this could be that the face mesh is too coarse or contains adjacent elements with large differences in scale。

Another reason can be that some subdomains in the geometry are too narrow with respect to the rest of the geometry.4032Failed to respect boundary element on geometry faceSee Error message 4031.4044Internal error boundary respecting See Error message 40314054Invalid topology of geometryThe geometry object cannot be used for creating a mapped mesh It must be subdivided4055Isolated entities foundEntities that are not connected to the boundaries of a geometry objects is found The mapped mesh generator does not support such isolated entities。
