Clear concept visuals from Tosca optimization studies.
SIMULIA Tosca is an engineering optimization suite for exploring structural layouts and fluid-flow concepts from FEA and CFD studies. Tosca Structure supports topology, shape, sizing, and bead optimization, while Tosca Fluid develops flow-path design concepts within a defined design space.

Tosca is used to explore engineering design directions before a part or flow component is finalized. In Tosca Structure, a team may evaluate topology results that suggest where material belongs, shape changes that refine a surface, sizing results for shell or beam thickness, or bead patterns that stiffen sheet metal. Tosca Fluid can produce an optimized concept for a defined flow task and design space. These outputs are valuable for analysis, yet the first useful view may be a density field, finite-element mesh, contour plot, or technical postprocessing image rather than a clear product visual.
RENDERCAD can turn a clean, selected Tosca view into presentation imagery without replacing the simulation work. Use a reconstructed or smoothed topology proposal, a readable bead-stiffened panel, or a clear exterior or cutaway view of an optimized flow passage as the input. The resulting visual can help a design team compare alternative lightweighting directions, explain a selected concept in a review, or prepare early communication for product, manufacturing, and stakeholder discussions. Keep loads, boundary conditions, performance values, manufacturability decisions, and validation results in Tosca and the connected engineering workflow; RENDERCAD is for communicating the approved visual direction, not proving engineering performance.
First, choose the Tosca result that tells one clear design story. For a structural study, this might be a smoothed topology proposal, a surface change, a thickness-focused part view, or the bead pattern on a sheet-metal panel. For a fluid study, choose a generated flow concept with a camera angle or cutaway that makes the passage layout understandable. Where appropriate, use geometry that has been reconstructed for design work instead of an ambiguous density or mesh-only view.
Set a neutral camera, hide solver panels, legends, loads, and dense annotations, then capture the part or component large enough for its material removal, ribs, beads, surfaces, or channels to remain legible. Upload that approved view to RENDERCAD and describe the communication goal, such as a clean concept-review image, an exploded engineering presentation, a manufacturing discussion visual, or a product-context illustration. Review the output against the selected Tosca result so the visible form stays aligned with the intended concept. Return to Tosca, the FEA or CFD model, and downstream CAD work for analysis, dimensions, performance claims, and final design approval.

RENDERCAD uses a maintained selection of image-generation models for different rendering tasks. Results can vary by model and input, so compare generated output with the source design before relying on geometry, materials, or dimensions.

The Render History page lets you browse and download retained images and videos. Storage duration depends on the account plan, so download assets you need before they expire.
Prompt "1950s appliance style, retro photography."
The core workflow starts from a selected 2D view, so it does not require native CAD-file conversion or source-model upload.
Reuse a clear history image and change the color instruction or reference. Treat the results as visual options rather than color-managed proof.
Describe the finish, gloss, grain direction, and lighting, or provide an authorized material reference. Generated reflections are visual approximations rather than physically verified material behavior.
It uses generative image models with screenshot or image inputs. Models and features can change over time, so current product documentation is the source of truth.
Video jobs consume credits based on current duration and model settings. Check the pricing page for current costs rather than comparing with an assumed outsourcing price.
Yes, if you are authorized to use it. A reference guides visual direction but does not guarantee style replication or geometry preservation.
Yes. Use a mask to target the background separately from the foreground product. Review both regions because generation can still alter unmasked content.
Reuse the same source image with authorized daytime and night lighting references or instructions. Compare both outputs with the source because lighting changes can also alter generated details.
Upload a CAD screenshot, real photo, or hand drawing and describe condensation or water droplets in the custom prompt. Generated placement and appearance vary, so iterate or mask a region when needed.
Add phrases like "Light from left," "Backlit," or "Top down lighting" to your custom prompt in RENDERCAD.
