View Fortran DLL content

Hi

I have a Fortran DLL file that I use for multibody dynamics simulations. 

I need to open this DLL file and tune some parameters. However, I do not have the original source code. 

Can someone show me how to open a compiled  DLL file?

Thank you

You can't - sorry. The DLL is a complex series of machine instructions that carry out what the original source code told it to. You have to find the original source, make the changes you want, and rebuild the DLL.

A lot of the original multi body problems coded in Fortran are present on the web, it depends on the method used. 

If you know the method you can probably find the code

So is it Runge Kutta Nystrom etc...
