Particle injection at fluid velocity

I'm injecting particles into a geometry using MPPICFoam (OpenFOAM-7) and the standard tutorial injection velocity is zero:
constant/kinematicCloudProperties: subModels { injectionModels { inletInjection { type patchInjection; U0 (0 0 0); etc. However, I want to inject particles at the continuum fluid velocity (U.air). When I replace the relevant line above with U0 U.air; it gives an error because it is looking for a '(' character. Is there some way of injecting at fluid velocity U.air?

Dear balloon,
Please note that the particle injection velocity should be specified in vector format, i.e., (# # #). If you want the particles to have the same initial velocity as the carrier, just input the same value as the one defined in 0/U.air. |
