All I can detect in 3D geometry view are functions to draw 3D objects. Simply I need to draw a circle on a suface of a block in order to ready boundary status on it. Whatever one can assist? Thanks,

Hi
set a work plane on the surface, and draw a circle in there, and so brand an embedded "surface"
It worked in v3.5, haven't tried information technology yet in v4

Good luck

Hi set up a work plane on the surface, and draw a circumvolve in at that place, and so make an embedded "surface" It worked in v3.5, haven't tried it even so in v4 -- Proficient luck Ivar

Hi,
In 4.ane, the "embedding" is implicit, so all you need to do is to create a piece of work plane that represents the block surface and so depict the circle on that piece of work plane'southward geometry. Then finalize the geometry (by moving on to the physics settings, for case). The circumvolve then defines a separate surface so that y'all tin can specify another boundary status in that area. See the attached screen shot.
Best regards,

Hello,
How do yous create this work plane on a curved surface, say on a sphere? I want to create a boundary area that is on the surface of a hemisphere. Capeesh any communication, cheers!

Hullo
you accept different options to define your workplane: the "quick mode" see the options, typically forth the coordinates, or on a surface, or via a set of points, upward to y'all to ascertain/precise for the programme

Expert luck

Hi you take unlike options to define your workplane: the "quick way" come across the options, typically along the coordinates, or on a surface, or via a set of points, up to yous to define/precise for the programme -- Skillful luck Ivar

Hi there
I am working with iv.0, I created a piece of work plane and drew a circle, but when I become over to one of the physics, the circle is gone and I cant fifty-fifty assign whatsoever physics to the circle. Any clues?
thank you!

Hi,In four.1, the "embedding" is implicit, and then all you demand to exercise is to create a work plane that represents the block surface and and then draw the circle on that work plane'southward geometry. And so finalize the geometry (past moving on to the physics settings, for example). The circle then defines a carve up surface and then that yous tin can specify another boundary condition in that area. See the attached screen shot.

Hullo at that place I am working with 4.0, I created a piece of work plane and drew a circumvolve, only when I go over to 1 of the physics, the circle is gone and I cant even assign any physics to the circumvolve. Whatsoever clues? thanks! liwah [QUOTE] Hi, In iv.ane, the "embedding" is implicit, so all you need to practise is to create a work plane that represents the cake surface and then draw the circle on that piece of work plane's geometry.

How-do-you-do Magnus,
Cheers for sharing! I came across this mail service as I encountered similar problems. I followed the steps and built a circumvolve on the piece of work plane. But when I become Helmholtz Equation (hzeq), the circle on that piece of work aeroplane is not included in the "all domain" selection. I cannot add source value to the circle. Is at that place any step I miss? How can I solve the problem? I'm using comsol v.1. Fastened is a figure showing the event.
Cheers in advance for your response!
Jianshan
How-do-you-do Magnus, Cheers for sharing! I came across this post every bit I encountered like bug. I followed the steps and built a circle on the work airplane. Only when I go Helmholtz Equation (hzeq), the circle on that work airplane is not included in the "all domain" option. I cannot add together source value to the circle. Is there any step I miss? How tin can I solve the problem? I'k using comsol 5.1. Attached is a figure showing the issue. Cheers in advance for your response! Jianshan

How-do-you-do Jianshan,
A disc is not three-dimensional, so it does not define a domain in 3D and you tin can therefore non assign an equation to exist solved on a 3D domain to it. In 3D, you could use a disc to assign a boundary condition, or a PDE defined on a surface, etc.
Best,
Jeff

Hello Austin,
In that case you do not use a work airplane: work planes are by definition planes, they cannot exist curved.
Instead, what yous do is that you create a 3-dimensional object that intersects with the curved surface so that their intersection creates the shape you need, as shown in the fastened toy model.
All-time,
Jeff
Hi Austin, In that instance you do not use a work airplane: work planes are past definition planes, they cannot exist curved. Instead, what you do is that you create a 3-dimensional object that intersects with the curved surface so that their intersection creates the shape you need, as shown in the attached toy model. All-time, Jeff

@Jeff Hiller.
Cheers for your responses to questions, years after. And also providing examples. This is the second time your response has been a aid.
