I am interested in modelling the flow and heat transfer in lattice heat exchangers. What tools and workflows does ANSYS have in place for this?

ANSYS has recently partnered with a company called nTopology that makes software for creating 3D models of complex lattice structures. One application is heat exchangers. More info on nTopology heat exchangers can be found here: https://ntopology.com/blog/2020/10/14/top-5-heat-exchanger-videos/ Below is a workflow that can be used to handle these geometries 1. Generate Solid/Fluid bodies in nTop 2. Generate/Export STL mesh in nTop 3. Import STL mesh into ANSYS Spaceclaim to define & capture the Boundary Condition surfaces 4. Import *.scdoc into ANSYS Fluent (with Meshing) using the Fault-tolerant meshing (FTM) workflow 5. Describe and identify various aspects/regions of the geometry 6. Generate the Volume Mesh + Inflation Layers (option for hexahedral/polyhedral/tet mesh) 7. Set up ANSYS CFD using the Named Selections/boundary faces captured in Spaceclaim NOTE: If you already have an STL model of a lattice heat exchanger, steps 3-7 can be used If you want to generate lattice heat exchanger geometry from scratch, ANSYS SpaceClaim also has a tool for creating a 3D lattice geometry to fill a volume For nTopology users, additional resources on using nTop geometries with ANSYS geometry, meshing and CFD tools can be found in nTopology’s learning center and training catalog: https://learn.ntopology.com/ https://support.ntopology.com/hc/en-us/articles/360062127673-How-to-export-your-design-to-Ansys-Fluent
