SubscriberHello,
I am using Ansys Fluent 17.2 for simulating CH4 combustion with air using the detailed GRI3.0 mechanism with DO radiation model on 2D axis-symmetric mesh.
I am using "Moment Method" to model soot. But as soon as I turn on the soot radiation option, Fluent gives me SIGSEGV error. I don't have any UDF hooked to my case so I am really clueless what can cause SIGSEGV ERROR in this case. Can anyone please help me with that?

Ansys EmployeeOthers report solving similar SIGSEGV issues by reinstalling the ANSYS product. If you can please try and upgrade to the latest release, ANSYS Student 18.2 in this case. Â

Error: FLOAT: invalid argument [1]: wrong type [not a number]

Error Object: 1.#inf

SubscriberThat was a silly mistake above. I used a single precision solver instead of double precision.

It is now working with Fluent 18.2. Thanks!
