![]() The boundary conditions come about when such differential equations are defined over a domain ( ). ![]() Â If we also add the information that this body was sitting around at time then that would constitute the initial conditions which would determine the trajectory that the body would take for all subsequent. A concise way of writing which is which is the differential statement of a simple mass moving under a force. Acceleration is how fast the velocity is changing and velocity is how fast the position of something is changing. For instance says force equals mass times acceleration. So how does it (getdp) work?Īll problems in mechanics are basically statements of differential quantities with certain initial conditions and certain boundary conditions. The learning curve is steep because there is scant documentation but it looks good in what it can do. I recently came across this software which, however, promises other things. Nothing too grave for people who just want to use them but for me they leave something to be desired. are very good I believe but they are quite expensive and, more importantly for me at least, they cloud the underlying mechanism of problem-solving. For instance, software like COMSOL, ANSYS, ABAQUS etc. There are a lot of options out there but they often require you to given an arm and a leg for them. I have been trying to find something similar for solving engineering problems. ![]() There is a price to be paid when it comes to the learning curve but LaTeX is an incredibly strong tool which just reeks hardcore utility. For instance, LaTeX leaves MS-Word in the dust. As far as software available to do scientific word processing is concerned, the paid stuff doesn't even come close to what is available for free. I am, therefore, always trying to figure out if things can be done with stuff available for free. I have found myself hating to pay for software, especially scientific ones.
