Hello and welcome to my homepage. Here I try to provide up to date information about myself. I am a post doctoral fellow of Mathematics department at the University of British Columbia. My supervisor is Professor I. Frigaard , one of the directors of Complex FLuids Laboratory. I was born in the beautiful city of Nahavand in western part of Iran and grew up in Tehran.
- 2011-2016: PhD student of Mechanical Engineering, UBC - Vancouver, Canada
- 2007-2009: M.Sc. in Mechanical Engineering, Sharif University of Technology - Tehran, Iran
- 2003-2007: B.Sc. in Mechanical Engineering, Sharif University of Technology - Tehran, Iran
My main field of research has been in FLuid Mechanics, particularly Non-Newtonian fluids. For a quick list:
- Visco-plastic fluids
- Thixotropy in visco-plastic fluids
- Applications of visco-plastic fluids in Oil/Gas industry: Well cementing, restart of waxy crude oil pipeline
- Biological and geophysical fluids
- Numerical methods: Finite Element/Volume methods, Lagrangian methods specially Smoothed Particle Hydrodynamics (SPH)
- Parallel Computing
- High performance software developing for scientific computing
Both numerical simulation and analytical studies are used, with more emphasis on simulation as valuable tool for gaining insight about the flow. I've found it very useful to learn a little bit about software engineering principles (e.g. cohesion/coupling) before starting to write a big in-house code developement.
Currently I'm mostly working with the following softwares:
- Rheolef: A very nice and high performance FEM library. The main thing I like about this library is that programs are really short. You can write a full Stokes flow solver with 20 lines of code.
- Matlab: I use it mostly for doing visualization and processing of my simulation results.
- Pelicans: A FEM/FVM framework. The main advantage of this frameworks is that it supports both FEM/FVM. In addition it comes with many useful applications. For example you can find LES, free surface, and other modules.
- FreeFEM++: is a partial differential equation solver using Finite Element Method. The main advantage of it is simplicity and ease of use with a large set of featuers.
