Hello Bill,
Thank you again for the example!
I tried that example and found a bug in the cgcns interface, where the plot
component “*lambda*” in the drop-down list actually shows the input of “mu”
in the command file, and the option “*s*” in the drop-down list actually
shows the input “lambda”. But in the plotStuff interface, the drop-down
menu shows correct options.
Since the JWL forms in Overture also include the ideal gas case when F=Z=0,
so I tried to modify the parameters in the explosive data file and set
ai1=ai2=0 in order to apply ideal gas law to the inert gas. But when I ran
the case, I found all the variables became 0 quickly within few time steps.
I was wondering why it did not work and if there is another way to get
ideal gas law from JWL EOS?
Thank you!
Best regards,
Heng

Hi Heng,
Jeff Banks has given me an example from the paper below and I will
send you the command files separately. I will add this example to the
distribution.

Hello Bill,
I was trying to simulate a solid munition explodes in the air, and found
the multi-fluid ignition and growth detonation modeling an appropriate
choice. I have put in all the required parameters for the mixture JWL EOS
and the second inert gas, according to the file
*setUserDefinedParameters.C*, but the simulation failed due to “*must
define gamma1, gamma2, cv1, cv2, pi1, and pi2 in command file*”. I do
not know to which components the index 1 and 2 denote, and am also
wondering if JWL EOS can be applied to the reaction products only?
Could you point me to an example using the multi-fluid ignition and
growth detonation modeling?
Thanks!
Best regards,
Heng
