I get an error message when trying to open my glTF-file in an external viewer
ソリューション番号: 1256 バージョン: 5.4After exporting a glTF-file from my COMSOL Multiphysics model, I get an error message when I try to open it in an external viewer. The most probable cause for this issue is that the external glTF-file you are using ...
Reducing the amount of solution data stored in a model
ソリューション番号: 1255 バージョン: すべてのバージョンMy models contain a lot of solution data, and I do not want my file sizes to get too large, it takes a lot of disk space. What can I do to reduce file size? Will this reduce the time it takes to solve the model? File ...
Controlling the Time Dependent Solver Timesteps
ソリューション番号: 1254 バージョン: すべてのバージョンI am solving a transient model and changed the stepsize in the Times: field in the Study Settings, but the solver is still taking exactly the same timesteps. It seems the timesteps that the solver is taking are not ...
Solving Wave-Type Problems with Step Changes in the Loads
ソリューション番号: 1244 対応: COMSOL Multiphysics バージョン: すべてのバージョンI am solving a transient model and am expecting the solution to oscillate over time in response to step changes in the loads. How should I set up such a model? What solver changes should I make? Certain models will ...

Running parametric sweeps, batch sweeps, and cluster sweeps from the command line
ソリューション番号: 1250 バージョン: すべてのバージョンThis solution describes how to launch a parametric sweep, a batch sweep, or a cluster sweep simulation in COMSOL Multiphysics® from the command line. ## Short Summary Model methods are presented as a concept to ...
"Data access entity removed" occurs in my application
ソリューション番号: 1247 バージョン: すべてのバージョンWhen running my application, I get the error "Data access entity removed". If a node is removed, Data Access to the node becomes invalidated. In general this error occurs if nodes used in Data Access are explicitly ...
Solving Models with Step Changes to Loads in Time
ソリューション番号: 1245 バージョン: すべてのバージョンHow should I model loads that change magnitude at a particular time? I am solving a transient model which has loads that change instantaneously in time, but the solver appears to be missing some of these changes in ...
Out of Memory
ソリューション番号: 1243 バージョン: すべてのバージョンThe error "Out of Memory" occurs. Of the available memory (RAM and virtual memory), one section, the Java heap, is reserved for Java. The rest of the memory will be available for meshing and solving. If you receive the ...
Unexpected Error Thrown by the Method Editor
ソリューション番号: 1242 対応: COMSOL Multiphysics, COMSOL Server バージョン: すべてのバージョンI run COMSOL Multiphysics on Windows 7. When trying to access the Method Editor in the Application Builder, I get an unexpected error. When opening the log file, the top of the stack trace looks like this: 2018-01 ...
