ic_quad args
Free surface meshing by the extended splitting line algorithm. The arguments come in keyword value pairs. Possible options are:
namevalue: Name of the mapping
q1/2/3/4/5:
1 = loop(s) from loop entities (default)
11 = loop(s) from surface entities
2 = loop from bar elements
3 = loop from subset of bar elements
4 = single loop from surface elements
5 = single loop from surface elements, replace old elements if new elements have higher quality, work only on free surface nodes
-1 = loop(s) from loop entities, create bar elements only
h1/2/3/4: Ignore holes if 1, mesh only holes if 2, mesh hull of surface elements if 3, or mesh gaps of surface elements if 4. The default is 0.
element1/2/3/4/5: If set to 4, every loop must have an even number of nodes on the edges in order to form an all-quadrilateral QUAD_4 mesh. This constraint will be automatically satisfied by creating an even number of nodes on each curve, or it will be dropped if the creation of one (option 1) or several (option 2) TRI_3 transition triangles is accepted. The meshing scheme can also generate TRI_3 triangle surface meshes (option 3), TRI_3 STL-like facets (option 5), structured QUAD_4 grids (option 6), and TRI_3 split STL facets (option 7). The default is 4.
innervalue: Preferred interior element size if > 0. Take from surface parameters if -1. The default is 0.
offsetn: Create n layers of offset elements. The default is 0. Argument "curve_family" can be used to limit offsetting to this family. A negative value will be only applied to curves with a given height parameter.
offset_hvalue: Relative value for the offset height. The default is 1. Use -1 to apply the curve parameters.
devvalue: Refine mesh up to three times to reduce surface deviation. Value defines the maximum surface deviation if not 0. The default is 0.
proj0/1: Project the new nodes onto the CAD surfaces if 1, or onto an isoparametric quadratic interpolation surface if 2. The default is 0.
itersmaximum: The mesh quality can be improved if additional smoothing steps are performed. With this option set, a pure Laplacian smoothing is used in which each interior node is moved to the centroid of its neighbors. In typical cases smoothing will converge after about six steps. The default maximum number of steps is 20. No complaints about inaccuracy if negative.
convervalue: The smoothing accuracy defines a convergence value which is related to the element sizes. The default value is 0.025. Uses an activity control for better performance if negative.
b_smooth0/1 : Smooth boundaries if 1. The default is 0.
improvement0/1/2/3 : Allow advanced improvement operations (node and element elimination, diagonal swapping, element merging and splitting, etc.) if set. The default is 0.
violatevalue : Allow a node to move off the surface by this value. The default is 0.
merge_tolvalue: Merge tolerance related to element size. The default is 0.1.
ele_tolvalue : The default element tolerance is 0. Set this violate geometry value to remove tiny elements, holes and loops. Given bunching will be protected if < 0.
boundary_tolvalue: The default boundary tolerance is -1. The mesher then applies above ele_tol on the boundary. Set this value in case you want to have an independent violate geometry tolerance for the boundary elements.
geo_tolvalue: The default looping tolerance is 0, which means that curves are only connected via identical endpoints. Set this value to enable free surface meshing to calculate the loop topology of inexact curves.
bunch0/1: Use node bunching from BAR_2 elements on curves if 1. The default is 0.
curve_familyname: Use curves from this family to define a virtual loop.
curve_family_2name: Use also curves from this family to define a virtual loop but never associate BAR_2 elements to these curves.
error_familyname : Move failed loops to this family.
offset_element_familyname: Move offset elements to this family.
materialname: Label new elements with this family name.
time_maxlimit: Stop the mesher if time limit has been exceeded. Default is infinite seconds.
ele_maxlimit: Stop the mesher if the element limit has been exceeded. Default is infinite number of elements.
try_twice0/1/-n: Try simple triangulation if 1 and meshing fails. First try simple triangulation and then retry without holes if 2. The default is 1. A negative value n limits simple triangulation to loops with number of nodes <= n. (for element type 2 and 3 only)
loopsnames: List of selected loops. The default is to mesh all loops.
blockvalue: Create a structured mesh instead of an unstructured up to this block quality if value > 0. The default value is 0. A suitable choice for hybrid meshes would be 0.2.
adjust_nodesvalue: Recompute number of nodes on edges such that all structured loops can be map meshed if set. Smooth nodes if > 1. The default value is 0.
adjust_nodes_maxvalue: Relative limit for node adjustment. The default value is 0.5 so that only those edges are adjusted where a maximum of 50% of the nodes need to be removed.
ignore_tp0/1: Ignore location of topological curve end points if set. The default value is 0.
board0/1 : Run improved meshing scheme for boards with many holes if set. The default value is 0.
complete_edges0/1/2: Complete missing edges in boundary loop if 1. 2 allows more than one loop from bar elements (q = 2 or 3). Broken loops are ignored. The default value is 0.
geo_id0/1: Create elements with family name of nearest surface if set. The default value is 0.
enn0/1: Estimated number of nodes if set. The default value is 0.
dormant0/1: Merge loops at dormant curves if set. The default value is 0.
patternvalue: Improve element pattern up to this angle if > 0. The default value is 150 degree.
simple_offset0/1: Do simple normal offsetting if set. The default value is 0.
four0/1: Force four-quad patterns at prescribed points if set. The default value is 0.
max_areavalue: Maximum element area if set. The default is 0.
max_lengthvalue : Maximum edge length if set. The default is 0.
min_anglevalue: Minimum angle if set. The default is 0.
max_nodesvalue: Maximum number of nodes if set. The default is 0.
max_elementsvalue: Maximum number of elements if set. The default is 0.
n_threadsvalue: Number of threads. The default is 0.
freeb0/1: Allow free bunching for patch independent surfaces if set. The default is 0.
snorm0/1: Orient elements to surface normals if set. The default is 0.
shape0/1: Element shape function, 0 is linear and 1 is quadratic. The default is 0.
