Overall though, a nice tutorial for beginners. It's better to bury the RRF body into the way and define any walls that it crosses as Stators (in the Wall boundary condition). If you are performing an internal calculation with a RRF, then best practice is to still extend the RRF body beyond the rotating impeller, even if it goes into the solid housing around it. I also typically recommend to define a volumetric mesh control using the RRF cylinder for these solutions. Thus having a few (say 2-3) computational cells between the rotating impeller body and the diameter of the rotating RF cylinder is of utmost importance.

The program SOLIDWORKS was used to generate a model of the wall geometries of. The idea here is that you are solving the RRF separately from the global (rectangular) computational domain and the solver needs to transfer information back and forth. propeller was analyzed in a computational fluid dynamics (CFD) solver. Thust would come from Force surface goal.īecause you are solving this problem using a rotating reference frame (RRF) approach, then in Step 2, you should make the cylindrical sketch (representing the RRF) slightly larger than the rotating propeller. Once again, Best thrust with less torque is the best choice.
The goal is to overcome the hull drag, with the minimum required torque. Then, with fixed RPM, a range of fluid speeds around the required Ship speed, must be studied(-Vz in this model). Īs first step, an initial guess of the ship service speed, propeller RPM and hull drag must be known. In quite a rough way the thing would go as follows. It means that flow motion, thrust and torque are going to be computed for the "static" propeller condition which for most cases is not practical.įor a real analisys, a parametric study would be the way to go. Trigger comes with two detecting modes, LIVE and ACCURATE.Jehan: Define a fluid speed along the Z axis (Negative sign as it is a speed "relative" to the propeller) Using the Leakage Suppression technology you can trigger a drum track with 100% accuracy even if this drum track has many loud bleeds from other drums. Trigger has the unique functionality to be set in a way that in can automatically be instructed to NOT trigger certain leakages on a drum track using its Leakage Suppression mode. Kick samples line up tight with the original kick drums, snare drum transients align perfectly, and tom fills come out exactly like the original tracks. When using Trigger, you will hear tight, phase accurate drum triggering without unwanted mistriggers, flamming, or phasing.
Other features include 2 detection modes, MIDI in/out, automation of detecting parameters, up to 127 different articulations per instrument, up to 127 velocity layers per instrument and up to 127 alternation hits per velocity layer, and a unique "Leakage Suppression" function. Each sample layer has parameters for customization such as velocity and dynamic control, attack, sustain, release and independent levels. This multi channel triggering functionality allows the user to recreate the sound of natural drums with real multitracked samples. Or, mix many direct mic samples to develop your own custom unique sounds. This means that in one instance of the plugin, you can seamlessly trigger multiple samples simultaneously such as a close mic sample, stereo overhead sample, and a stereo room mic samples. Trigger has a phase accurate multi layered triggering engine. Slate Digital Trigger is the next generation drum replacement VST/RTAS/AU plugin.
