Project your design split lines onto the matched surfaces. Use clean, high-degree curves for the projection to avoid introducing jagged edges into the trim boundary. Inspect the trim edge to ensure it is crisp and free of micro-steps. The Advanced Corner Blend

For comprehensive documentation, refer to the IceStorm manual (available at hedmen.org/icestorm-doc) which covers iCE40 1K and 8K bitstream formats, tile structures, and programming procedures.

Isophotes map lines of equal light intensity across your model. Sharp breaks in the lines indicate a error. Tangent but sharp steps indicate a G1 boundary.

Build a transitional patch using the or N-Sided Surface tools.

Which does your design specification require?

Real ICEM Surf masters spend most of their time using the tool. This is where digital modeling becomes digital sculpting. The Point Snapping and Moving Strategy Project your design split lines onto the matched surfaces

The workflow in ICEM CFD is not just about producing a mesh; it’s about control. It provides the ability to selectively refine areas of interest—like trailing edges of turbines or fillets in automotive parts—without the computational cost of global refinement.

In a parametric system, if you want to make a car hood longer, you must edit the sketches. In ICEM Surf, you manipulate the topology globally.

Click in the IM Surf panel. ICEM will generate the surface mesh based on your settings. Tangent but sharp steps indicate a G1 boundary

The iCE40 architecture includes multiple clock networks with programmable skew control. By isolating clock domains, you can:
