I am using Eulerien model in Ansys Fluent for modeling diesel spray in a constant volume chamber. In fluent injection, particle initial conditions can be read from an external file. I write six injections in a one file, the file has the following form:
((x y z u v w diameter temperature mass-flow) injection0:ID)
When I run the simulation it give the error
“ERROR reading particle 0 for injection: injection-0”
Can anybody suggest me the solution to this problem?
Thanks in advance.
Hi,
this post is contradictory.
On one hand side you write, that you use Eulerian multiphase flow modeling.
On the other hand side you write about an injection file. But injection files in ANSYS Fluent are used for initial conditions of droplets/particles in !_Lagrangian_! particle tracking, i.e. LPTM (which is called DPM for some reasons in ANSYS Fluent).
The error message suggests, that nevertheless you have setup somehow Lagrangian Particle Tracking in your simulation and from the error message it seems, that there might be still some syntax error in the specification of the injection conditions. At least the solver is not able to read a valid dataset from your given injection file, when it tries to set the initial conditions for the 1st discrete particle track.

Dr. Th. Frank.
Thanks @ Dr. Th. Frank for your reply.
In eulerian multiphase modeling I am choosing the dense discrete phase model. kindely suggest me the correct syntax of injection file. i used this dataset
((x y u v diameter temperature mass-flow) name)
((0.00012 0.00000 4.15 0.0 0.0001025 373.0 0.0000367)injection0:10)

((0.00012 0.000103 0.00 0.0 0.0001025 373.0 0.000366879)injection5:10)
Please carefully read the ANSYS Fluent users guide for the format of the injection file. Please mind in the above error message:
((x y z u v w diameter temperature mass-flow) injection0:ID)
