Material Library
Being able to create a simulation that mirrors reality depends not onlyon accurate geometries and physics but also the specification ofreal-world materials. The Material Library automates the process foraccessing material data while still offering flexibility.
Based on the Material Property Database (MPDB) from JAHM Software,Inc., the Material Library contains information for materials such asminerals, rocks, soil, metal alloys, oxides, steels, thermalinsulators, semiconductors, and optical materials. It includes:
* 2500 materials and 20,000 property functions, each described as apiecewise polynomial of some variable, typically temperature.
* A search feature that lets you look for materials by name, UNS number, or DIN number
* Product information

o CSTR Startup Comsol3.2就不需要Matlab的支持了，不过很不稳定
程序很大，但好像有用的不多，很多都要自己开发
3.3听说稳定了，我拿到了试用版
又变大了，启动一次就得几分钟
我用他算了个渗流问题，速度超慢 现在3.4都出了，据说支持64位的计算。
大家的福音啊。
