SIMPLE (or SIMPLER) fortran code
 
Hello, I am a chemical engineering. I am writing a fortran code to simulate the motion of particle in a fluidized bed (a system where many hundreds of particles are moved by a flow of a gas, usually air), using the Discrete Element Method. To do this work, I need to use a subroutine ables to solve (in unsteady condition) the pressure and air flow velocity fields. Since the main aspect of my work is the modelling of interparticle forces, I would like to save time, using an available code. Hence, I am searching the source of such a code (I think SIMPLE or SIMPLER algorithm could be a good choice, is so ?)

Many thanks in advance

Francesco

Re: SIMPLE (or SIMPLER) fortran code
 
It has been a long time (1985) since I used SIMPLER for my graduate project. I obtained a portion of the FORTRAN source code that included subroutines for solving velocity and pressure from Dr Laurence S Caretto at California State University, Northridge, who was my advisor at the time. I communicated with him sometime last year by email, and believe he is still teaching at CSUN. He might have a source code available.

Hello. SIMPLE might not be the best approach if you use the same time step size for both fluid flow and particle caluculations. In many cases, much smaller time step size is required for particle calculations in DEM. SIMPLE, inplicit, allows you to have relative larger time step size, is not advantageous in terms of that point.

Hello, I am a mechanical engineering.I need to use a subroutine ables to solve (in unsteady condition) 3-D fluid flow (the pressure and velocity and temperature) fields in cylindrical coordinate . Can you send me the source code for SIMPLE / SIMPLER scheme (preferably on fortran) so that I can get & proceed from it.
please send me through my email, ahazbavi@ymail.com.
