  When simulating an explosion using dualcese, I noticed abnormal temperatures, with extensive high-temperature areas reaching tens of thousands of degrees. Is this due to issues with the material parameter settings or does the software not support explosion temperature simulation? The model uses units of meters (m), kilograms (kg), and seconds (s), with a uniform mesh size of 5mm. Other parameters were set based on the material parameters for the 3D LX-17 explosive from the official example case. In my simulation, the mass of the LX-17 explosive is 2.5 kg. In cese, the JWL equation of state requires input of Cv. The help documentation states that this parameter is "heat capacity." Increasing it did reduce the temperature, but I'm unsure whether this adjustment is correct.
