Solid Model Settings Window

Model File⚓︎

Specifies the tolerance for building solid model items and Boolean operations

Specifies the angle between spring elements to create connecting volumes

A connecting volume appears between spring elements if the angle is larger than the specified value.
> 0, default = 0.0873 (angle in radian; about 5°)

Specifies the minimal spring length of the model

Corner fillets and process data settings can create springs of very short length which cause meshing problems for the finite element model export to FEM.
Spring volumes (SV) with a short length are combined with an adjacent connecting volume (CV).
≥ 0, default = 0.1 (Units of length, e.g. µm)

Specifies the minimal corner fillet radius of the model

The specified corner fillet radius in the Process Data Settings window is enlarged or reduced by the mask undercut settings. Concave corners get larger radiuses and convex corners get smaller radiuses. If the undercut is bigger than the corner radius, a sharp tip appears at the convex corners.
A minimal corner radius can be defined to force corner fillets on all spring elements.
> 0, default = 0.1 (Units of length, e.g. µm)

Extends the size of the spring connection volumes in spring directions

Connecting volumes can obtain short lines if complicated spring designs are linked at one connecting point and corner fillets are switched off.
The connecting volumes can be slightly extended by a spring connection offset to improve the mesh quality for a finite element model export to FEM.
≥ 0, default = 0

Combines circular and straight lines at the fillet of spring connecting volumes

Corner fillets at opposite sides of the springs can have different sizes in case of asymmetric structures. Straight and circular or elliptical lines appear in the corner region.
Both lines can be combined to improve the finite element mesh quality in FEM.
The parameter defines the length of straight lines which are combined with circular lines.
≥ 0, default = 1 (Units of length, e.g. µm)

Defines the tilt angle at spring-mass-junctions

The interface between springs and masses can be design by an additional connection volume with a straight chamfer or a circular corner fillet to avoid stress concentrations (see Offset Length Spring-Mass-Junction).
0 ≤ tilt_angle < π/2 [rad], default = 0.52 (about 30°)

Defines the offset length at spring-mass-junctions

Defines the tilt angle at spring-jump-junctions (sudden change of the spring)

The interface between springs with different beam width (spring-jump-junction) is designed by an additional connection volume with a straight chamfer or a circular corner fillet to avoid stress concentrations (see Offset Length Spring-Jump-Junction).
0 ≤ tilt_angle < π/2 [rad], default = 0.21 (about 12°)

Defines the offset length at spring-jump-junctions

The offset length defines the extension of the connecting volume in beam axis direction for straight chamfer.
≥ 0, default = 0

Activates or deactivates the tilt angle at spring-mass- and spring-jump-junctions for subsequent “Build Solids” operations

Defines the depth of an interface volume at the connection of mass bodies to spring elements

Additional interface volumes (IV) at masses are necessary for bodies which consist of two or more material domains at the interface region to springs.
Different material domains are separated by internal lines in mass bodies. As a consequence, attached springs are difficult to mesh with hexahedral elements after the finite element model export to FEM.
If the replacement depth parameter is non-zero, an additional volume with the specified depth appears at the interface and allows for hexahedral elements in adjacent springs.
≥ 0, default = 2 (Units of length, e.g. µm)
