When I create a circular pattern the original features i patterned disappears, how to fix it?

Today doing the pattern circulation, do not work, so I went to website to look for clues , find two approach.

1. When I create a circular pattern the original features i patterned disappears, what is causing this?
https://forum.solidworks.com/thread/42537
The expert suggest to It is in feature mode, I just went ahead and used the circular patterns in my sketchs, thanks.


2. The holes show up in the preview function while creating the pattern, but disappear as you complete the pattern.
the expert also suggest use in feature mode, but here is the part I dont understand though

The problem you're seeing is due to the fact that the original Hole Wizard feature you created just shows the original component it cut in the Feature scope for components affected by the Hole Feature. When the feature is circular patterned the pattern feature gives no option for additional parts to intersect. To fix the issue modify your Hole Wizard Assembly feature to include any components that you want to cut when patterning the Assembly feature.

The original Hole won't cut the other components but when it's patterned the holes will appear in any components selected in the Feature Scope Group box. These components must be selected manually in the original feature see attached file.

maths in solidworks

lol, today using solidwork to draw a stent using wrap function,

it end up myone has a small gap in between, it shows the advantage of using divide operator, as it always leave the decimal place.

maths not good enough

Periodic boundy condition code

ok, as I promise to solve the periodic condition problem for one of my collegues, so i decide give it a try.
http://www.cfd-online.com/Forums/fluent/28770-periodic-boundary-condition-shadow-pairs.html

use TUI: mesh/modify-zones/make-periodic choose your periodic boundary IDs as the input. Everything should go well and complete cells match on both sides should be found.

difference between fourier transform and wavelets

Haiz, sometimes when all the hope fade, you have to look for something which can cheers you up.
anyway, you still have to live for quite a long time.

so i move out the first step for digital signal processing
http://math.stackexchange.com/questions/279980/difference-between-fourier-transform-and-wavelets
et us say we are looking at the signal of the light emitted from a traffic light. So for some time it will be red, and for some time it will be green (ignore the yellow for now). If we take the Fourier transform of the observed frequency, we can say that

At some time the traffic light shows red. (We know frequency to infinite precision, and that the red part of the signal is non-zero.)
At some time the traffic light shows green.
But a functioning traffic light would have either red or green shown at a time, and not both. And if the traffic light malfunctions and shows both lights at the same time, we would still see from the Fourier transform

At some time the traffic light shows red.
At some time the traffic light shows green.
But if we take the wavelet transform we can sacrifice frequency precision to gain temporal information. So with the wavelet transform done on the working traffic light we may see

At parameter w which corresponds roughly to t(w) being 1 o'clock sharp and k(w) corresponding to red, the wavelet transform is large and non-zero. This can be taken to mean that sometime around 1 o'clock sharp (could be exactly 1 o'clock, could be 1 minute past, could be 30 second before) the light showed a color that is more or less red (could be a little bit purple, or maybe a little bit amber).
At parameter w which corresponds roughly to t(w) being 1 o'clock sharp and k(w) corresponding to green, the wavelet transform is almost zero. This can be taken to mean that at all the times around 1 o'clock (say plus or minus 2 minutes) the traffic light does not show any hint of green.
At parameter w which corresponds roughly to t(w) being five minutes past 1 and k(w) corresponding to green, the wavelet transform is large and non-zero. This would indicate that around 1:05 (maybe 1:06, or 1:04) the light shined greenish (could have a tinge of teal or a bit of yellow in it).
This would tell us that not only can the traffic light show both red and green lights, that at least at around 1 o'clock the light is working properly and only showing one light.

ansys fsi problem I

O.K .so recently stuck in mesh in ansys fluid structure interaction.the mesh in transient structure does not work well.
It looks like there is still a long way to go.
keep on pops up
error updating cell solution in the transient structural system.
i guess most probably will need some luck
This error mostly returned while you have intersecting bodies in your problem geometry. just one of those bodies should be meshed and the other ones should be used as "Body of influence" at least in one "Sizing" feather.

I hope this could solve your problem.
Good Luck

another one
The target body that you want to scope to needs to be selected as patch conforming tetrahedron - if you don't do this it will not modify the meshing (To make target body patch conforming right click on mesh, select insert -> method -> select target body --> then select method tetrahedron)
http://www.cfd-online.com/Forums/ansys-meshing/96051-bodies-influence-settings-problem.html

put the bracket beside the variable.

ok, so try orcad parameter sweep,


keep on pop up error,
**** INCLUDING SCHEMATIC1.net ****
* source RESISTORS
R_RS N02282 VL 47k TC=0,0
V_V1 N02282 0 10V
R_R1 0 VL rvariable TC=0,0
-----------------------------$
ERROR(ORPSIM-16152): Invalid number
.PARAM rvariable=10k

**** RESUMING "global sweep.cir" ****
.END

at the end is because i did not put the bracket beside the rvariable which is supposed to be parameter.

hehe, so stupid...

Part VIN has no 'STIMULUS' property

Ok. so today I run the PSpice, and face the problem
INFO(ORNET-1041): Writing PSpice Flat Netlist C:\Cadence\SPB_16.6\OpenAccess\resistors-PSpiceFiles\SCHEMATIC1\SCHEMATIC1.net
ERROR(ORNET-1110): Part VIN has no 'STIMULUS' property

constantly make the error, whether i change Vac, Vdc, but life is always like this, you never realize you make the mistake only after you make it.

Hehe. I have extra component in the bottom page, that's why i have that error.
once I remove the extra component of power source, the error disappear.

remember at the start, you create a project based on simple.obj.using the design template.at the corner you can see the following figure, remove it.

as it create extra power source, that's why your simulation is not running, once you remove, our circuit is completed and in a closed loop, so everything is working fine.

hope it helps.
