Thermal calculations which scrutinize behavior caused by differences in temperature is used to study solid bodies as well as the flow surrounding such bodies. Both planes are often so closely interrelated that an integrated approach is logical.

During thermal analysis, we calculate and examine heat transfer by

Heat conductance (depending on the material’s thermal conductivity)
Convection (transportation by a flow)
Radiation (propagation of waves)

During this calculation, we take chemical processes (endothermic and exothermic reactions) into account. It occurs due to the combustion of melting-solidification or condensation-vaporization.
