When I defined my first step outputs in matlab code as a variable and used it as input to solve next step , it didn't work. It only could get number but I need continuous update.
Dear Saba Mortezazadeh
While it is not uncommon to face challenges when using the COMSOL LiveLink with MATLAB, the specific issue you described could have various causes. Here are a few potential reasons and suggestions to help address the problem:
1. Variable Update: Ensure that you are updating the variable that represents the output of the first step in MATLAB. In some cases, the variable may not be updating as expected, leading to incorrect or outdated inputs for the next step. Verify that the variable is being properly updated before using it as an input for the subsequent solver.
2. Timing and Synchronization: Confirm that the LiveLink interface between COMSOL and MATLAB is synchronized properly. The LiveLink interface should be set up to update the variables and solutions in real-time to maintain continuous communication between the two software platforms. Review the synchronization settings and verify that the communication between COMSOL and MATLAB is functioning as intended.
3. Output File Format: Check the output file format settings in COMSOL. Ensure that the output file format chosen allows for continuous updates and can be read by MATLAB in real-time. Adjust the output file format if necessary to enable the desired continuous update of variables.
4. Solver Configuration: Review the solver settings in COMSOL to ensure they are appropriately configured for the desired continuous solution update. The solver parameters, such as the time step size, convergence criteria, and output intervals, may need adjustments to achieve the desired level of continuous update.
5. LiveLink Version Compatibility: Ensure that you are using compatible versions of COMSOL and MATLAB, including the corresponding LiveLink versions. Compatibility issues between different software versions can sometimes lead to unexpected behavior or limited functionality. Upgrading to the latest versions or ensuring compatibility between versions may help resolve the issue.
If the problem persists, consider reaching out to the technical support resources provided by COMSOL or consulting with experts familiar with using COMSOL LiveLink and MATLAB for more specific guidance tailored to your particular setup and requirements.
