The immune system is a collection of billions of cells that travel through the bloodstream. They move in and out of tissues and organs, defending the body against foreign bodies (antigens), such as bacteria, viruses and cancerous cells.There are two types of lymphocytes :B cells-produce antibodies which are released into the fluid surrounding the bodyâs cells to destroy the invading viruses and bacteria. T cells (see picture opposite) - if the invader gets inside a cell, these (T cells) lock on to the infected cell, multiply and destroy it.here are two types of lymphocytes : B cells-produce antibodies which are released into the fluid surrounding the bodyâs cells to destroy the invading viruses and bacteria.

Geometry is an interesting one as Comsol has links with the majority of mainstream design or engineering software. These âLiveLinkâ tools allow integration with data, not only from SolidWorks, Pro/Engineer and Inventor but other common engineering tools such as Matlab.hile the heavy simulation tools used for FEA or CFD have been widely adopted, systems simulation is still a relatively niche technology. Al Dean takes a look at Comsol Multiphysics, which aims to change just that.
