*REACTION RATE

Define the reaction rate for an ignition and growth equation of state.

This option is used to define the reaction rate for an ignition and growth equation of state. It is required when the EOS, TYPE=IGNITION AND GROWTH option is used. The REACTION RATE option should appear immediately after the EOS or the GAS SPECIFIC HEAT option.

This page discusses:

There are no parameters associated with this option.

 

Data lines to define the reaction rate
