@@arsitech-ltd Hello sir, How do you apply gravity using SPH? Can you apply it straight to the whole model like most normal simulations or is there a separate technique because of the SPH implementation nature in abaqus(ex. applying iton the fluids' node set) Thank you
In this case modeling only tank is sufficient..as tank rigidly attached with vehicle. But if tank free to move (attached with some breakable connections) and effect of sloshing one want to see on whole vehicle..then only entire vehicle need to import.
@@arsitech-ltd Thank you, sir! I have some problems about poost-processing. My SPH paiticle are showing up big, I want to narrow it. Do you konw how to do it? and what Post-processing software is good to see SPH particle.
Dear, Instead of directly defining PC3D elements it is recommended to define conventional continuum finite element types C3D8R, C3D6, or C3D4 and check on convert to particle option in Meshing...abaqus automatically convert them to particle elements at the beginning of the analysis or during the analysis depends on ur input. If u used Pre-processing from Hypermesh..then procedure is different.
Dear, I want to modify my words. Sloshing height can be calculated by both methods. But tracking of node (node that reachs to peak height or other) is possible with SPH only. There are some relationship between sloshing height and energy envolved. I nit remember exactly... please dind related details on internet.
Superb job
Hi. Did you apply gravity for that? because the hydrostatic condition must be applied before moving of the truck.
Yes.

Thank you
Dear,
Apply directly. No special requirements.
@@arsitech-ltd thank you sir !
Cool simulation. Did you need to model the vehicle, though? Modeling the tank was sufficient, wasn't it?
In this case modeling only tank is sufficient..as tank rigidly attached with vehicle. But if tank free to move (attached with some breakable connections) and effect of sloshing one want to see on whole vehicle..then only entire vehicle need to import.
@@arsitech-ltd Thanks
Amazing CAE, sir. Can you apply "fsi" in this case? if the supposed event that it's necessary to see stresses in the chassis
Dear,
You can use both SPH or FSi for the same.
@@arsitech-ltd could you do the tutorial of how you did the configuration in your video? i would thankfully a lot
Dear,
Already 3 video uploaded on CEL (for FSi).. different example but you can understand concept.
@@arsitech-ltd if i analyze a tank trailer, and i put the tank like rigid. the load would transmitted to the chassis?
Yes...if only tank is Rigid and chassis is deformable body...then with proper connection load will transmit to chassis.
Hi , Can you tell me what the parameters of water are? The result of my simulation is very ugly.
Dear,
along with density (1000 kg/m3) and viscosity (8.90e-4) EOS us-up material model used
C0=1500
S=0
Gamma=0
@@arsitech-ltd Thank you, sir!
I have some problems about poost-processing. My SPH paiticle are showing up big, I want to narrow it. Do you konw how to do it? and what Post-processing software is good to see SPH particle.
Great! Can you show what type of interaction between fluid with tank?
Its a friction less general contact.
@@arsitech-ltd How long did you take to run this model? SPH is really faster than CEL method?
It tooks around 1 hr with 16 processor (ryzen 7 4800h).
Yes for same number of nodes SPH is fast than CEL.
@@arsitech-ltd I don't know type of element for SPH. Should use PC3D or C3D4 element. which one better?

Nice work! Is it possible to recognize particles of the free surface and extract the sloshing height of a specific position?
With SPH possible but with CEL not possible.
Here this technique is SPH based.
@@arsitech-ltd Could you please explain how to get sloshing heights with SPH?

There are some relationship between sloshing height and energy envolved. I nit remember exactly... please dind related details on internet.
如何对液体罐车中的液体进行建模？
Dear,
I used SPH technique here.
bro...can you please explain " full vehicle integration" with example in your next video...it ll be very helpful...
Dear
Full vehicle assembly will take months in Pre-processing. Here only main frame considered.
@@arsitech-ltd okay..thanks...
