Hi

I am trying to simulate hypergolic compounds combustion [UDMH(liq)+N2O4(g)]. since UDMH is not present in the fluent database therefore i have manually added UDMH in the fluent database file (propb.scm) as fluid material, mixture of UDMH+N2O4 and droplet-particle with the available UDMH properties on the internet.

I am using EDM - Species Transport model for turbulent combustion modeling. i am trying to simulate the following combustion reaction.

2C2H8N2 + N2O4 = 2CO2 + 4H2O + 3N2

Problem occurs when i select the udmh-n2o4 mixture (manually added in the database) the following message appears in the fluent console.

error: CDR: invalid argument [1]: wrong type [not a pair]
error: object: #F

can anyone help in correcting this.
