Unable to load some of the D3plot due to Invalid header entry ndim #52

Open mystic-comets opened 2 months ago

Raise RuntimeError(f"Invalid header entry ndim: {self.raw_header['ndim']}") RuntimeError: Invalid header entry ndim: 7653631721478

Could you give a bit more information about in which line the issue was raised, and what you mean by 'some' of the D3plot? Anything that could help reproduce the issue. I use the library regularly and haven't found any similar issues, so these would help.

Thanks for providing a file, that is great. I unfortunately won't be able to attend this issue soon. So either stay patient, try to fix it yourself or someone else here can jump in.

image it unable to convert binary format to ascii format so it shows error for ndim (values are high),

ballaln commented 2 months ago

You might be right. It appears that there might be a conversion error occurring within the '_read_file_buffer' function. According to both the LS-DYNA documentation and the Lasso code snippet, the variable 'ndim' should hold a value of either 2 or 3, depending on the dimensionality of the data. In this specific case, it should have been 3. I am not sure if I could help you out on this.

I attempted to view the data in LS-PrePost and HyperView, where it successfully opened and I could access the data. However, I encountered an issue with the Lasso library as I couldn't extract the data from it. Can you assist in resolving this problem?
