I have converted the caesar 5.1 file into a neutral file and tried to convert this neutral file to input file in caesar 5.0 but it is showing

error like this one

Error Processing Element Section,line # 73.

Please help on this error

There are differences in the input between 5.00 and 5.10 (new additions), this is why 5.00 can't open a 5.10 input file. So if you want to go back in versions, you have to manually edit the neutral file and remove anything that was added in the newer version that didn't exist in the older version.

Hi Richard
I cant find something to remove on that file can you explain more.
thanks

In the neutral file for Version 5.10 we included (2) more lines of data (for each element) which contain the "hot modulus" values. We should have added these for Version 5.00, but we missed this.

So, to take a 5.10 neutral file back to 5.00, you'll need to delete these two lines for every element in the model.

There other differences too. You just need to compare the documentation between different versions (I don't keep track of file format changes).
