[Bug] Minor Bugs in Custom Components #695

Open Musharafus1986 opened 3 days ago

Hi Daniel, Hopefully you are well.

I have noticed the following bugs when creating custom compounds with DWSIM (some to consider fixing in next release, Pics are attached)

  1. Critical volume is calculated as 0 when its value is 0.0572. All other critical parameters are displayed correctly. This is observed repeat when i created multiple different custom compounds.

  2. Wrong units are given under the equation in Cp. Correct units are kJ/kg-K

  3. Unlike other properties, Thermal conductivity does not accept copy paste from excel and needs manual typing.

Enhancement suggestion: It would be useful if there is a way to permanently add custom unit operations once they are created. This would greatly improve simulation speed instead of loading them every time we start the simulation.

Let me know if you have questions.

Thanks Musharaf

Another one, D2 gas data needs tobe corrected. Enthalpy and Gibbs energy of formation should be 0. LHV should be same as H2

Vapour Pressure data is also not correct. Correct Data is as follow
