Introduction of PDPDMagic heat exchanger analysis sytem of on demand tankless water heaters 
Before thermal stress analisys calculation of fulud dynamics by PfMagic is necessary.
PFmagic is fulid dynamics anslysis software for design heat exchanger of tankless water heaters.
User can do quite easy parameter fluid dynamics study by PFMagic. .
Meshing (Completely Automatic) fin by PfMagic Data
Transpoprt to PDmagic from PFmagic is quite easy .
User can easily know how Thermal stress at pipe and body caused by thermal expansion.
Examples of Result of Finite element method at heatexchanger
Following Picures are Full Finite Element Model of Heat Exchanger Generated from PfMagic data
Example of Crack Risk at the wall caused by thermal expansion.(Thermal Stress)
Get knowing how fluid dynamics effects to Fin and Pipe and walls Etc.
thermal expansion at fin match depends on fin temperature
and Fin temperature is match affected by fluid dynamics.
Example od Mises STRESS at wall.
Finite Element Simulaion Model of On demmand Dual type Heat exchangers.
Case study of Heat Exchanger length and Thermal stress.
Example of pipe and fin transformation caused by thermal expansion.
Result of Thermal Stress Calculated From Finite Element Simulation.
User can select Calculix as a Finite Element Method solver.
