Coupled Eulerian Lagrangian (CEL) - Fluid Structure Interaction (FSi), Part - 02 Elastic DAM & Fluid

Thanks for this interesting video. One question concerning the geostatic stress. Why is it necessarry to define it? Does it really affect the results? in Benchmark-file (for example) it is not defined. Your explanation would be greatly appreciated.

[@yuzhao5764]

Why did you set up "H-F" in step of Predefined Field? If you set up the gravity of water, the water pressure to wall sholud have emerged. Is the set-up of stress to wall repeated again ?

[@arsitech-ltd]

Dear, Gravity load start working from step 1 and onwards. So settings the predefined H-F will insure the pressure load from initial step itself...later gravity play.

Very Helpful and interseting Lectures Sir.. I'm going to be simulating the flow through soil-type materials, specifically looking at permeability. Could you suggest some videos or platforms that would be beneficial for this? Your guidance would be greatly appreciated.

[@arsitech-ltd]

I never tried permeability with Abaqus FSi.

[@asheshchoudhury548]

Which type of element did you use for the stopper?

[@arsitech-ltd]

C3D8 element as i remember.

How to model a fluid filled enclosed structure (fluid at certain uniform static pressure and enclosed structure is made of balloon) and that system subjected to a water jet to calculate the deformation and stress.. Your kind suggestion is needed in this regard

[@arsitech-ltd]

Dear, Methodology remain same. You need to model structure (balloon) surrounded by Eularian domain. Use volume fraction tool to fill structure (go with 3rd video of CEL on my channel). Apply appropriate BCs.

Sir, my stopper is bending drastically nd moreover stopper is shown in white colour I dont know why I have checked my values numerous no. of times. What does it mean when an instance is shown in white in results and not showing colour contours nd the reason behind its that much bending. please reply

[@arsitech-ltd]

Dear, Make sure correct youngs modulus and density for the stopper. Check unit consistency. White is representing results not applicable to that component. Volfraction results only for Eularian domain. If you will check stress/strain/displacement than contour will be visible for stopper.

Imagine if you have two hard plate and you want to squeeze paste between them. Is this possible with FSI method?

[@tharindudissanayake9317]

Can u please create a video of bulk material discharge simulation in a elevated silo?

[@arsitech-ltd]

I hope you are talking about soil ? SPH is better option.

id like to perform the structural analysis of windshield by FSI so plz help me regarding the process bcz in u tube there's so many vedio regarding the co-execution of cfd and fea but did't have any detailed explanation. help me regarding this . thank you

[@arsitech-ltd]

Dear, How can i help you?

[@041_vedant_aero8]

@@arsitech-ltd in 2020 version theres no cfd solver and apart from that i have no idea how to do so bcz in all FSI tutorial they show the process done by means of star ccm+ and abaqus , i have downloaded the both software but don't know how to execute the analysis

[@arsitech-ltd]

Dear, Abaqus alone capable to solve FSi problems. Let me know what is your analysis boundary conditions for windshield. You can also drop a mail.

Hello, Could you please send me your email; I have a problem simulating a marine energy recovery system (CEL modeling). How can I send you the model and discuss it?
