Hello everyone,

I have recently conducted simulations inAbaqus 2022 Explicit regarding convective heat transfer through water jet impingement on a metal plate. There is always a problem make me really frustrated: The water on the plate is never shown in the visualiszation.

I built the CAE-model like followings: First I made two 3D-diformabale-solid-extrusion parts for water and metal plate. Then I made a 3D-eulerian-extruded solid for the euler-space. Then I assemblied them. Their shapes and the location are showed in the picture 1 and picture 2. The circle on the euler-space part is the nozzle from which the water jet sprays out and its diameter is 1mm. The distance between nozzle and the metal plate is 6mm. Later I defined two materials named water and copper. For the property of water, I gave ABAQUS the basic parameters of density, EoS-Us-Up, dynamic viscosity and thermo parameters like conductivity and specific heat. In section manager I created water section as eulerian and copper section as solid, homogeneous. Finally I used the section assignment to assign the water section to the euler-space part and copper section to the metal plate. For the water part, I didnt assign any material on it for this would be used later as reference part in descrete-field→volume fraction tools. After the material definition I create the step as Dynamic, Temp-Displacement, Explicit and set the step time as 0.05 second. I also edited the output-settings to make there would be an output after every 0.05 second and all other settings I left as default. In the Interaction section, I simply defined a Contact-mechanical normal behaviour with all settings in default (hard contact) as the only interaction property and I used this property in the Interaction manager to create a General Contact (Explicit) with the contact domain all* with self. And then I meshed the Euler-space and the metal plate automatically. The element on the Euler-space was EC3D8RT and the element type on the Plate is C3D8RT. I set the length of element both euler-space and plate so small to 0.25 mm in order to make sure the water on the plate can be captured. After that I defined the metal plate as rigid body and fixed it in the euler-space and also defined the velocity for the water jet as 5.1m/s in the boundary condition manager. In the end I implement the volume fraction tool to create a descrete field, took the euler-space part and water part as eulerian part instance and reference part instance. And in the load-predefined field sector I created a material assignment with euler-space part again as eulerian part instance and the used the descrete field I just created.

Actually the simulation time was not only 0.05 seconds for I implemented a Python script to start restart jobs and let the ABAQUS continuously analyse the water flowing on the plate. The problem is, after the whole analyse, that only the water jet can be seen in each ODB file. I tried all methode but the water flowing on the metal plate can never be shown just like what was shown in picture 3-5 (Water should already spread out on the plate in the time of 0.05s). So I would really like to ask, did I make the CAE model for this analyse correctly and if I made it correctly then why is it not possible to show the water on the plate? I would greatly appreciate it if you could answer my questions!
