Failed to open the SimBiology project only for Model Analyzer

I tried to open the SimBiology file via SimBiology MATLAB 2024b, which was created on 21 Mar by the version 2024b, but failed to open Model Analyzer while successfully opened Model Builder. Alert was popped up as attached in this inquery.

This phenomenon has happened only recently. Also, it is reproduced several times. An old file I saved on 12 Mar can be opened without any issues.

I have found MathWorks-internal knowledgebase content with this error message, but for an older release. The reason is described as the project file became corrupt. A multi-step workaround is provided, but I do not understand the workarond good enough to publish it here.

Please contact MathWorks support pointing to this thread.

Thanks for the comment.

By some trials using the old file with no issues, I've just realized that if a lot of analysis records in a model analyzer file are deleted at the same time and then the file is saved, this error will happen. Probably the file collapses.

I further tried to delete analysis records one by one and the file is saved. Then, the file was successfully opend without error. So, I can continue my work. Thanks.

Hi, Sotaro,

I am sorry to hear that you have run into errors loading your project. You understanding is correct - the Model Analyzer uses additional project info. re: programs, results and imported data. Errors related to this content will not affect the Model Builder.

Based on the screenshot that you have shared, it looks like you may have a datasheet and/or a fit program that is not in a valid state. If you delete your datasheets, you may be able to bypass the error without needing to delete your analysis results. If you can share your project with us, either by messaging me directly or through Technical Support, I can investigate futher.
